The entire dc.js library is scoped under dc name space. It does not introduce anything else into the global name space.
Majority of dc functions are designed to allow function chaining, meaning it will return the current chart instance whenever it is appropriate. Therefore configuration of a chart can be written in the following style.
chart.width(300)
.height(300)
.filter("sunday")
The API references will highlight the fact if a particular function is not chainable.
Clear all filters on every chart within the given chart group. If the chart group is not given then only charts that belong to the default chart group will be reset.
Re-render all charts belong to the given chart group. If the chart group is not given then only charts that belong to the default chart group will be re-rendered.
Redraw all charts belong to the given chart group. If the chart group is not given then only charts that belong to the default chart group will be re-drawn. Redraw is different from re-render since when redrawing dc charts try to update the graphic incrementally instead of starting from scratch.
This function can be used to in Coordinate Grid Chart to define units on x axis. dc.units.integers is the default x unit scale used by Coordinate Grid Chart and should be used when x range is a sequential of integers.
This function can be used to in Coordinate Grid Chart to define ordinal units on x axis. Usually this function is used in combination with d3.scale.ordinal() on x axis.
This function generates xunit function in floating-point numbers with the given precision. For example if the function is invoked with 0.001 precision then the function created will devide a range [0.5, 1.0] with 500 units.
This function is design to trigger throttled event function optionally with certain amount of delay(in milli-seconds). Events that are triggered repetitively due to user interaction such as the dragging of the brush might over flood library and cause too much rendering being scheduled. In this case, using this function to wrap your event function allows the library to smooth out the rendering by throttling event flood and only respond to the most recent event.
chart.renderlet(function(chart){
// smooth the rendering through event throttling
dc.events.trigger(function(){
// focus some other chart to the range selected by user on this chart
someOtherChart.focus(chart.filter());
});
})
Base chart is an abstract functional object representing a basic dc chart object for all chart and widget implementation. Every function on base chart are also inherited available on all concrete chart implementation in dc library.
Set or get width attribute of a chart. If the value is given, then it will be used as the new width.
If no value specified then value of the current width attribute will be returned.
Set or get height attribute of a chart. If the value is given, then it will be used as the new height.
If no value specified then value of the current height attribute will be returned.
Set or get dimension attribute of a chart. In dc a dimension can be any valid crossfilter dimension. If the value is given, then it will be used as the new dimension.
If no value specified then the current dimension will be returned.
Set or get group attribute of a chart. In dc a group is a crossfilter group. Usually the group should be created from the particular dimension associated with the same chart. If the value is given, then it will be used as the new group.
If no value specified then the current group will be returned. If name is specified then it will be used to generate legend label.
Clear all filters associated with this chart.
Execute in scope d3 single selection using the given selector and return d3 selection result. Roughly the same as:
d3.select("#chart-id").select(selector);
This function is not chainable since it does not return a chart instance; however the d3 selection result is chainable from d3's perspective.
Execute in scope d3 selectAll using the given selector and return d3 selection result. Roughly the same as:
d3.select("#chart-id").selectAll(selector);
This function is not chainable since it does not return a chart instance; however the d3 selection result is chainable from d3's perspective.
Set the svg root to either be an existing chart's root or the first element returned from a d3 css string selector. Optionally registers the chart within the chartGroup. This class is called internally on chart initialization, but be called again to relocate the chart. However, it will orphan any previously created SVG elements.
Return the dom ID for chart's anchored location
Returns the root element where a chart resides. Usually it will be the parent div element where svg was created. You can also pass in a new root element however this is usually handled as part of the dc internal. Resetting root element on a chart outside of dc internal might have unexpected consequences.
Returns the top svg element for this specific chart. You can also pass in a new svg element however this is usually handled as part of the dc internal. Resetting svg element on a chart outside of dc internal might have unexpected consequences.
Remove the chart's SVG elements from the dom and recreate the container SVG element.
Set or get filter printer function. Filter printer function is used to generate human friendly text for filter value(s) associated with the chart instance. By default dc charts shipped with a default filter printer implementation dc.printers.filter that provides simple printing support for both single value and ranged filters.
Turn on/off optional control elements within the root element. dc.js currently support the following html control elements.
Set or get animation transition duration(in milliseconds) for specific chart instance. Default duration is 750ms.
Invoke this method will force the chart to re-render everything from scratch. Generally it should be only used to render the chart for the first time on the page or if you want to make sure everything is redrawn from scratch instead of relying on the default incremental redrawing behaviour.
Calling redraw will cause the chart to re-render delta in data change incrementally. If there is no change in the underlying data dimension then calling this method will have no effect on the chart. Most of the chart interaction in dc library will automatically trigger this method through its internal event engine, therefore you only need to manually invoke this function if data is manipulated outside of dc's control; for example if data is loaded on a periodic basis in the background using crossfilter.add().
Check whether is any active filter or a specific filter is associated with particular chart instance. This function is not chainable.
Filter the chart by the given value or return the current filter if the input parameter is missing.
// filter by a single string
chart.filter("Sunday");
// filter by a single age
chart.filter(18);
Return all current filters. This method does not perform defensive cloning of the internal filter array before returning therefore any modification of returned array will affact chart's internal filter storage.
Set or get filter handler. Filter handler is a function that performs the filter action on a specific dimension. Using custom filter handler give you the flexibility to perform additional logic before or after filtering.
// default filter handler
function(dimension, filter){
dimension.filter(filter); // perform filtering
return filter; // return the actual filter value
}
// custom filter handler
chart.filterHandler(function(dimension, filter){
var newFilter = filter + 10;
dimension.filter(newFilter);
return newFilter; // set the actual filter value to the new value
});
Set or get the key accessor function. Key accessor function is used to retrieve key value in crossfilter group. Key values are used differently in different charts, for example keys correspond to slices in pie chart and x axis position in grid coordinate chart.
// default key accessor
chart.keyAccessor(function(d) { return d.key; });
// custom key accessor for a multi-value crossfilter reduction
chart.keyAccessor(function(p) { return p.value.absGain; });
Set or get the value accessor function. Value accessor function is used to retrieve value in crossfilter group. Group values are used differently in different charts, for example group values correspond to slices size in pie chart and y axis position in grid coordinate chart.
// default value accessor
chart.valueAccessor(function(d) { return d.value; });
// custom value accessor for a multi-value crossfilter reduction
chart.valueAccessor(function(p) { return p.value.percentageGain; });
Set or get the label function. Chart class will use this function to render label for each child element in the chart, i.e. a slice in a pie chart or a bubble in a bubble chart. Not every chart supports label function for example bar chart and line chart do not use this function at all.
// default label function just return the key
chart.label(function(d) { return d.key; });
// label function has access to the standard d3 data binding and can get quite complicated
chart.label(function(d) { return d.data.key + "(" + Math.floor(d.data.value / all.value() * 100) + "%)"; });
Turn on/off label rendering
Set or get the title function. Chart class will use this function to render svg title(usually interrupted by browser as tooltips) for each child element in the chart, i.e. a slice in a pie chart or a bubble in a bubble chart. Almost every chart supports title function however in grid coordinate chart you need to turn off brush in order to use title otherwise the brush layer will block tooltip trigger.
// default title function just return the key
chart.title(function(d) { return d.key + ": " + d.value; });
// title function has access to the standard d3 data binding and can get quite complicated
chart.title(function(p) {
return p.key.getFullYear()
+ "\n"
+ "Index Gain: " + numberFormat(p.value.absGain) + "\n"
+ "Index Gain in Percentage: " + numberFormat(p.value.percentageGain) + "%\n"
+ "Fluctuation / Index Ratio: " + numberFormat(p.value.fluctuationPercentage) + "%";
});
Turn on/off title rendering
Renderlet is similar to an event listener on rendering event. Multiple renderlets can be added to an individual chart. Every time when chart is rerendered or redrawn renderlet then will be invoked right after the chart finishes its own drawing routine hence given you a way to override or modify certain behaviour. Renderlet function accepts the chart instance as the only input parameter and you can either rely on dc API or use raw d3 to achieve pretty much any effect.
// renderlet function
chart.renderlet(function(chart){
// mix of dc API and d3 manipulation
chart.select("g.y").style("display", "none");
// its a closure so you can also access other chart variable available in the closure scope
moveChart.filter(chart.filter());
});
Expire internal chart cache. dc.js chart cache some data internally on a per chart basis so it can speed up rendering and avoid unnecessary calculation however under certain circumstances it might be useful to clear the cache e.g. after you invoke crossfilter.add function or if you reset group or dimension post render it is always a good idea to clear the cache to make sure charts are rendered properly.
Attach dc.legend widget to this chart. Legend widget will automatically draw legend labels based on the color setting and names associated with each group.
chart.legend(dc.legend().x(400).y(10).itemHeight(13).gap(5))
All dc chart instance supports the following listeners.
This listener function will be invoked before chart rendering.
This listener function will be invoked after chart finish rendering including all renderlets' logic.
This listener function will be invoked before chart redrawing.
This listener function will be invoked after chart finish redrawing including all renderlets' logic.
This listener function will be invoked after a filter is applied, added or removed.
This listener function will be invoked after a zoom is triggered.
Marginable is a mixin that provides margin utility functions for both the Row Chart and Coordinate Grid Charts.
Get or set the margins for a particular coordinate grid chart instance. The margins is stored as an associative Javascript array. Default margins: {top: 10, right: 50, bottom: 30, left: 30}.
The margins can be accessed directly from the getter.
var leftMargin = chart.margins().left; // 30 by default
chart.margins().left = 50;
leftMargin = chart.margins().left; // now 50
Coordinate grid chart is an abstract base chart designed to support a number of coordinate grid based concrete chart types, i.e. bar chart, line chart, and bubble chart.
Get or set the range selection chart associated with this instance. Setting the range selection chart using this function will automatically update its selection brush when the current chart zooms in. In return the given range chart will also automatically attach this chart as its focus chart hence zoom in when range brush updates. See the Nasdaq 100 Index example for this effect in action.
Get or set the scale extent for mouse zooms.
Get or set the a zoom restriction to be limited at the origional extent of the range chart
Get or set the root g element. This method is usually used to retrieve the g element in order to overlay custom svg drawing programatically. Caution: The root g element is usually generated by dc.js internals, and resetting it might produce unpredictable result.
Set or get mouse zoom capability flag (default: false). When turned on the chart will be zoomable through mouse wheel . If range selector chart is also attached zooming will also update the range selection brush on associated range selector chart.
Retreive the svg group for the chart body.
Get or set the x scale. x scale could be any d3 quatitive scales. For example a time scale for histogram or a linear/ordinal scale for visualizing data distribution.
// set x to a linear scale
chart.x(d3.scale.linear().domain([-2500, 2500]))
// set x to a time scale to generate histogram
chart.x(d3.time.scale().domain([new Date(1985, 0, 1), new Date(2012, 11, 31)]))
Set or get the xUnits function. xUnits function is the coordinate grid chart uses to calculate number of data projections on x axis such as number bars for a bar chart and number of dots for a line chart. This function is expected to return an Javascript array of all data points on x axis. d3 time range functions d3.time.days, d3.time.months, and d3.time.years are all valid xUnits function. dc.js also provides a few units function, see Utilities section for a list of built-in units functions. Default xUnits function is dc.units.integers.
// set x units to day for a histogram
chart.xUnits(d3.time.days);
// set x units to month for a histogram
chart.xUnits(d3.time.months);
Custom xUnits function can be easily created using as long as it follows the following inteface:
// units in integer
function(start, end, xDomain) {
// simply calculates how many integers in the domain
return Math.abs(end - start);
};
// fixed units
function(start, end, xDomain) {
// be aware using fixed units will disable the focus/zoom ability on the chart
return 1000;
};
Set or get the x axis used by a particular coordinate grid chart instance. This function is most useful when certain x axis customization is required. x axis in dc.js is simply an instance of d3 axis object therefore it supports any valid d3 axis manipulation. Caution: The x axis is typically generated by dc chart internal, resetting it might cause unexpected outcome.
// customize x axis tick format
chart.xAxis().tickFormat(function(v) {return v + "%";});
// customize x axis tick values
chart.xAxis().tickValues([0, 100, 200, 300]);
Turn on/off elastic x axis. If x axis elasticity is turned on, then the grid chart will attempt to generate and recalculate x axis range whenever redraw event is triggered.
Set or get x axis padding when elastic x axis is turned on. The padding will be added to both end of the x axis if and only if elasticX is turned on otherwise it will be simply ignored.
Get or set the y scale. y scale is typically automatically generated by the chart implementation.
Set or get the y axis used by a particular coordinate grid chart instance. This function is most useful when certain y axis customization is required. y axis in dc.js is simply an instance of d3 axis object therefore it supports any valid d3 axis manipulation. Caution: The y axis is typically generated by dc chart internal, resetting it might cause unexpected outcome.
// customize y axis tick format
chart.yAxis().tickFormat(function(v) {return v + "%";});
// customize y axis tick values
chart.yAxis().tickValues([0, 100, 200, 300]);
Turn on/off elastic y axis. If y axis elasticity is turned on, then the grid chart will attempt to generate and recalculate y axis range whenever redraw event is triggered.
Turn on/off horizontal grid lines.
Turn on/off vertical grid lines.
Set or get y axis padding when elastic y axis is turned on. The padding will be added to the top of the y axis if and only if elasticY is turned on otherwise it will be simply ignored.
Set or get the rounding function for x axis. Rounding is mainly used to provide stepping capability when in place selection based filter is enable.
// set x unit round to by month, this will make sure range selection brash will
// extend on a month-by-month basis
chart.round(d3.time.month.round);
Get or set padding in pixel for clip path. Once set padding will be applied evenly to top, left, right, and bottom padding when clip path is generated. If set to zero, then the clip area will be exactly the chart body area minus the margins. Default: 5
Turn on/off the brush based in-place range filter. When the brush is on then user will be able to simply drag the mouse across the chart to perform range filtering based on the extend of the brush. However turning on brush filter will essentially disable other interactive elements on the chart such as the highlighting, tool-tip, and reference lines on a chart. Default value is "true".
Zoom this chart to focus on the given range. The given range should be an array containing only 2 element([start, end]) defining an range in x domain. If the range is not given or set to null, then the zoom will be reset. For focus to work elasticX has to be turned off otherwise focus will be ignored.
chart.renderlet(function(chart){
// smooth the rendering through event throttling
dc.events.trigger(function(){
// focus some other chart to the range selected by user on this chart
someOtherChart.focus(chart.filter());
});
})
Color chart is an abstract chart functional class created to provide universal coloring support as a mix-in for any concrete chart implementation.
Retrieve current color scale or set a new color scale. This function accepts both d3 color scale and arbitrary color array. By default d3.scale.category20c() is used.
// color scale
chart.colors(d3.scale.category20b());
// arbitrary color array
chart.colors(["#a60000","#ff0000", "#ff4040","#ff7373","#67e667","#39e639","#00cc00"]);
Set or get color accessor function. This function will be used to map a data point on crossfilter group to a specific color value on the color scale. Default implementation of this function simply returns the next color on the scale using the index of a group.
// default index based color accessor
.colorAccessor(function(d, i){return i;})
// color accessor for a multi-value crossfilter reduction
.colorAccessor(function(d){return d.value.absGain;})
Set or get the current domain for the color mapping function. This allows user to provide a custom domain for the mapping
function used to map the return value of the colorAccessor function to the target color range calculated based on the
color scale. You value can either be an array with the start and end of the range or a function returning an array. Functions
are passed the chart in their this
context.
// custom domain for month of year
chart.colorDomain([0, 11])
// custom domain for day of year
chart.colorDomain([0, 364])
// custom domain function that scales with the group value range
chart.colorDomain(function() {
[dc.utils.groupMin(this.group(), this.valueAccessor()),
dc.utils.groupMax(this.group(), this.valueAccessor())];
});
Stackable chart is an abstract chart introduced to provide cross-chart support of stackability. Concrete implementation of charts can then selectively mix-in this capability.
Stack a new crossfilter group into this chart with optionally a custom value retriever. All stacks in the same chart will share the same key accessor therefore share the same set of keys. In more concrete words, imagine in a stacked bar chart all bars will be positioned using the same set of keys on the x axis while stacked vertically. If name is specified then it will be used to generate legend label.
// stack group using default accessor
chart.stack(valueSumGroup)
// stack group using custom accessor
.stack(avgByDayGroup, function(d){return d.value.avgByDay;});
An abstraction provides reusable functionalities for any chart that needs to visualize data using bubbles.
Get or set bubble radius scale. By default bubble chart uses d3.scale.linear().domain([0, 100])
as it's r scale .
Get or set the radius value accessor function. The radius value accessor function if set will be used to retrieve data value for each and every bubble rendered. The data retrieved then will be mapped using r scale to be used as the actual bubble radius. In other words, this allows you to encode a data dimension using bubble size.
Get or set the minimum radius for label rendering. If a bubble's radius is less than this value then no label will be rendered. Default value: 10.
Get or set the maximum relative size of a bubble to the length of x axis. This value is useful when the radius differences among different bubbles are too great. Default value: 0.3
This chart is a concrete pie chart implementation usually used to visualize small number of categorical distributions. Pie chart implementation uses keyAccessor to generate slices, and valueAccessor to calculate the size of each slice(key) relatively to the total sum of all values.
Examples:
Create a pie chart instance and attach it to the given parent element.
Parameters:
Return: A newly created pie chart instance
// create a pie chart under #chart-container1 element using the default global chart group
var chart1 = dc.pieChart("#chart-container1");
// create a pie chart under #chart-container2 element using chart group A
var chart2 = dc.pieChart("#chart-container2", "chartGroupA");
Get or set the maximum number of slices the pie chart will generate. Slices are ordered by its value from high to low. Other slices exeeding the cap will be rolled up into one single Others slice.
Get or set the inner radius on a particular pie chart instance. If inner radius is greater than 0px then the pie chart will be essentially rendered as a doughnut chart. Default inner radius is 0px.
Get or set the radius on a particular pie chart instance. Default radius is 90px.
Get center x coordinate position. This function is not chainable.
Get center y coordinate position. This function is not chainable.
Get or set the minimal slice angle for label rendering. Any slice with a smaller angle will not render slice label. Default min angel is 0.5.
Concrete bar chart/histogram implementation.
Examples:
Create a bar chart instance and attach it to the given parent element.
Parameters:
Return: A newly created bar chart instance
// create a bar chart under #chart-container1 element using the default global chart group
var chart1 = dc.barChart("#chart-container1");
// create a bar chart under #chart-container2 element using chart group A
var chart2 = dc.barChart("#chart-container2", "chartGroupA");
// create a sub-chart under a composite parent chart
var chart3 = dc.barChart(compositeChart);
Whether the bar chart will render each bar centered around the data position on x axis. Default to false.
Manually set fixed gap (in px) between bars instead of relying on the default auto-generated gap. By default bar chart implementation will calculate and set the gap automatically based on the number of data points and the length of the x axis.
Concrete line/area chart implementation.
Examples:
Create a line chart instance and attach it to the given parent element.
Parameters:
Return: A newly created line chart instance
// create a line chart under #chart-container1 element using the default global chart group
var chart1 = dc.lineChart("#chart-container1");
// create a line chart under #chart-container2 element using chart group A
var chart2 = dc.lineChart("#chart-container2", "chartGroupA");
// create a sub-chart under a composite parent chart
var chart3 = dc.lineChart(compositeChart);
Get or set render area flag. If the flag is set to true then the chart will render the area beneath each line and effectively becomes an area chart.
Get or set the radius (in px) for data points. Default dot radius is 5.
Data count is a simple widget designed to display total number records in the data set vs. the number records selected by the current filters. Once created data count widget will automatically update the text content of the following elements under the parent element.
Examples:
Create a data count widget instance and attach it to the given parent element.
Parameters:
Return: A newly created data count widget instance
For data count widget the only valid dimension is the entire data set.
For data count widget the only valid group is the all group.
var ndx = crossfilter(data);
var all = ndx.groupAll();
dc.dataCount(".dc-data-count")
.dimension(ndx)
.group(all);
Data table is a simple widget designed to list crossfilter focused data set (rows being filtered) in a good old tabular fashion.
Examples:
Create a data table widget instance and attach it to the given parent element.
Parameters:
Return: A newly created data table widget instance
Get or set the table size which determines the number of rows displayed by the widget.
Get or set column functions. Data table widget uses an array of functions to generate dynamic columns. Column functions are simple javascript function with only one input argument d which represents a row in the data set, and the return value of these functions will be used directly to generate table content for each cell.
chart.columns([
function(d) {
return d.date;
},
function(d) {
return d.open;
},
function(d) {
return d.close;
},
function(d) {
return numberFormat(d.close - d.open);
},
function(d) {
return d.volume;
}
]);
Get or set sort-by function. This function works as a value accessor at row level and returns a particular field to be sorted
by. Default value: function(d) {return d;};
chart.sortBy(function(d) {
return d.date;
});
Get or set sort order. Default value: d3.ascending
chart.order(d3.descending);
A concrete implementation of a general purpose bubble chart that allows data visualization using the following dimensions:
Examples:
Create a bubble chart instance and attach it to the given parent element.
Parameters:
Return: A newly created bubble chart instance
// create a bubble chart under #chart-container1 element using the default global chart group
var bubbleChart1 = dc.bubbleChart("#chart-container1");
// create a bubble chart under #chart-container2 element using chart group A
var bubbleChart2 = dc.bubbleChart("#chart-container2", "chartGroupA");
Turn on or off elastic bubble radius feature. If this feature is turned on, then bubble radiuses will be automatically rescaled to fit the chart better.
Composite chart is a special kind of chart that resides somewhere between abstract and concrete charts. It does not generate data visualization directly, but rather working with other concrete charts to do the job. You can essentially overlay(compose) different bar/line/area charts in a single composite chart to achieve some quite flexible charting effects.
Examples:
Create a composite chart instance and attach it to the given parent element.
Parameters:
Return: A newly created composite chart instance
// create a composite chart under #chart-container1 element using the default global chart group
var compositeChart1 = dc.compositeChart("#chart-container1");
// create a composite chart under #chart-container2 element using chart group A
var compositeChart2 = dc.compositeChart("#chart-container2", "chartGroupA");
Combine the given charts into one single composite coordinate grid chart.
// compose the given charts in the array into one single composite chart
moveChart.compose([
// when creating sub-chart you need to pass in the parent chart
dc.lineChart(moveChart)
.group(indexAvgByMonthGroup) // if group is missing then parent's group will be used
.valueAccessor(function(d){return d.value.avg;})
// most of the normal functions will continue to work in a composed chart
.renderArea(true)
.stack(monthlyMoveGroup, function(d){return d.value;})
.title(function(d){
var value = d.value.avg?d.value.avg:d.value;
if(isNaN(value)) value = 0;
return dateFormat(d.key) + "\n" + numberFormat(value);
}),
dc.barChart(moveChart)
.group(volumeByMonthGroup)
.centerBar(true)
]);
Geo choropleth chart is design to make creating crossfilter driven choropleth map from GeoJson data an easy process. This chart implementation was inspired by the great d3 choropleth example.
Examples:
Create a choropleth chart instance and attach it to the given parent element.
Parameters:
Return: A newly created choropleth chart instance
// create a choropleth chart under "#us-chart" element using the default global chart group
var chart1 = dc.geoChoroplethChart("#us-chart");
// create a choropleth chart under "#us-chart2" element using chart group A
var chart2 = dc.compositeChart("#us-chart2", "chartGroupA");
Use this function to insert a new GeoJson map layer. This function can be invoked multiple times if you have multiple GeoJson data layer to render on top of each other. If you overlay mutiple layers with the same name the new overlay will simply override the existing one.
Parameters:
// insert a layer for rendering US states
chart.overlayGeoJson(statesJson.features, "state", function(d) {
return d.properties.name;
});
Set custom geo projection function. Available d3 geo projection functions. Default value: albersUsa.
Return all GeoJson layers currently registered with thit chart. The returned array is a reference to this chart's internal registration data structure without copying thus any modification to this array will also modify this chart's internal registration.
Return: An array of objects containing fields {name, data, accessor}
Remove a GeoJson layer from this chart by name
Return: chart instance
Bubble overlay chart is quite different from the typical bubble chart. With bubble overlay chart you can arbitrarily place a finite number of bubbles on an existing svg or bitmap image (overlay on top of it), thus losing the typical x and y positioning that we are used to whiling retaining the capability to visualize data using it's bubble radius and coloring.
Examples:
Create a bubble overlay chart instance and attach it to the given parent element.
Parameters:
Return: A newly created bubble overlay chart instance
// create a bubble overlay chart on top of "#chart-container1 svg" element using the default global chart group
var bubbleChart1 = dc.bubbleOverlayChart("#chart-container1").svg(d3.select("#chart-container1 svg"));
// create a bubble overlay chart on top of "#chart-container2 svg" element using chart group A
var bubbleChart2 = dc.compositeChart("#chart-container2", "chartGroupA").svg(d3.select("#chart-container2 svg"));
Set the underlying svg image element. Unlike other dc charts this chart will not generate svg element therefore bubble overlay chart will not work if this function is not properly invoked. If the underlying image is a bitmap, then an empty svg will need to be manually created on top of the image.
// set up underlying svg element
chart.svg(d3.select("#chart svg"));
Set up a data point on the overlay. The name of a data point should match a specific "key" among data groups generated using keyAccessor. If a match is found (point name <-> data group key) then a bubble will be automatically generated at the position specified by the function. x and y value specified here are relative to the underlying svg.
Concrete row chart implementation.
Create a row chart instance and attach it to the given parent element.
Parameters:
Return a newly created row chart instance
// create a row chart under #chart-container1 element using the default global chart group
var chart1 = dc.rowChart("#chart-container1");
// create a row chart under #chart-container2 element using chart group A
var chart2 = dc.rowChart("#chart-container2", "chartGroupA");
Get or set the vertical gap space between rows on a particular row chart instance. Default gap is 5px;
Get or set the elasticity on x axis. If this attribute is set to true, then the x axis will rescle to auto-fit the data range when filtered.
Get or set the x offset (horizontal space to the top left corner of a row) for labels on a particular row chart. Default x offset is 10px;
Get of set the y offset (vertical space to the top left corner of a row) for labels on a particular row chart. Default y offset is 15px;
Legend is a attachable widget that can be added to other dc charts to render horizontal legend labels.
chart.legend(dc.legend().x(400).y(10).itemHeight(13).gap(5))
Examples:
Set or get x coordinate for legend widget. Default value: 0.
Set or get y coordinate for legend widget. Default value: 0.
Set or get gap between legend items. Default value: 5.
Set or get legend item height. Default value: 12.
Get or set the label for Others slice when slices cap is specified. Default label is Others.
Get or set the grouper funciton that will perform the insersion of data for the Others slice if the slices cap is specified. By default the grouper function implements the following logic, you can and should change this function to match your data structure. If set to a falsy value, no others will be added;
function (data, sum) {
data.push({"key": _othersLabel, "value": sum });
};
A display of a single numeric value.
Examples:
Create a Number Display instance and attach it to the given parent element.
Unlike other charts, you do not need to set a dimension. Instead a valid group object must be provided and valueAccessor that is expected to return a single value.
Parameters:
Return: A newly created number display instance
// create a number display under #chart-container1 element using the default global chart group
var display1 = dc.numberDisplay("#chart-container1");
Calculate and return the underlying value of the display
Get or set a function to format the value for the display. By default d3.format(".2s");
is used.


I've been working as a software engineer in Silicon Valley for the last 11 years. During that time, I've worked for three startups, and seen failure, acquisition and LinkedIn going IPO. My main strengths right now are in Java backend programming, digital security, SQL and feature development. I have done and would like to do more Ajax/CSS/HTML5 work, as well as learn other dynamic languages such as ruby or python.
Although I am not currently looking for another position, I do like to hear about exciting new companies that are close to Morgan Hill. If your opportunity is north of Mountain View, I am not interested. When I do evaluate companies, I look for an engineering or lead position that has a fun engineering process, challenging problems of scale for a back-end engineer, some front-end work, and a great team of collaborative genuine people.
To find out more about my professional life, visit my blog, visit my LinkedIn profile or see my work experience on this site.
I hold a Ph.D. in Computer Science and Electrical Engineering from the University of Queensland. You can read my Ph.D. thesis and browse publications here.
In a previous life as a budding academic, I was an advocate for formal methods in software development. I worked with people at the Object-Z and RESOLVE communities, making research techniques more practical. I still am an advocate for formal methods, but without language and tool support, its a losing battle.

While we would love to show off the farm, we simply do not have the time
and are not set up to provide private tours during working farm hours. We are a working farm,
every minute of the day is planned.  When you come to our Farm Front Porch
Market Hours, there are ropes and cones blocking off areas of the farm for this reason. Please
do not enter blocked off areas when coming to pick up your products. We are only open for tours
through Airbnb Experiences, or during our Farm Days. For more information about our Airbnb
Experiences and Farm Days, visit our Airbnb Page.
If you are looking for a local farm and petting zoo, we highly recommend HorsePower for Kids Animal Sanctuary.
Please pull into the barn driveway and PARK ON YOUR IMMEDIATE LEFT! It will be the second one on your left and it is an unpaved driveway. Please do not continue down the driveway with any vehicle, block the driveway, or park off our property. If there is a lot of traffic, please follow the instructions of the parking attendant.
You can walk through the wooden entry gate on the FAR right. When you come to our Farm Front Porch Market Hours, there are ropes and cones blocking off areas of the farm for a reason. Please do not enter blocked off areas when coming to pick up your products. We ask that you walk up to the barn front porch where you can ring the bell (yes, a literal bell) and someone will come to help you.
Please do not let your children loose! There are many hazards on the farm and it would break our hearts if anything happened. We have no liability insurance so enter at your own risk! Unattended children will be gifted with two kittens, a super large Mountain Dew and allowed to climb the manure pile! Just kidding, but you catch the drift…
Again, we ask that you please do not pass beyond the rope in the barnyard or the gates. We are only open for viewing the animals during Farm Days and the Airbnb Experiences.
Last, please do not bring your furry friends, as we already have too many of them!
We offer Farm Tours through Airbnb Experiences! All tours must be scheduled through Airbnb Experiences!
The walking tour starts at the duck enclosure (they are up front) and continues with a look at our prize-winning chickens! You will learn about the various breeds and why we have them (production and show) and we will show you how we gather eggs from the nests. Next, we will continue to the barn area where we will first visit with our dry stock (non-milking). I will explain the different breeds of goats, their origins, and show the difference between our dry goats and our milking line. Guests will be allowed to pet the animals and we will supply animal cookies for you to feed them. You will have the opportunity to pet, snuggle and love on the goats.
From time to time there are baby goats, ducks, chicks, and bunnies. We cannot plan what we will have at any one time, but we foster cats so most of the time there are kittens to see. If we have baby goats, guests can learn to bottle feed the babies if they wish. Guests will view the milking parlor and we will explain how we produce the milk from beginning to end. The tour will conclude with a sampling of fresh artisan cheese made here on the farm! The tour lasts approximately 2 hours, with the last 20 minutes spent sampling our various goat cheeses and products.
Schedule your tour at Airbnb Experiences.
Two days a year we put our best “hoof” forward, spiff up the farm, and invite our friends and customers in for Farm Day! We have live music, food available for purchase, our products available for sale, as well as several vendors who share our sustainable green mission. Our Team Members on site can answer any questions you may have about the farm, provide milking demonstrations, and an opportunity to meet and interact with the animals.
As you roam around the barnyard, you will meet the girls that produce the milk, the Goosepack, Muffy the Feline Farm Supervisor, Grandpa JJ the rescued alpaca and baby goat babysitter, Tommy Turkey and his harem, and all the other critters. We like to showcase not only our animals, but also our Team Members on Farm Day and show our gratitude for their dedication to a job well done! Overall, it is a fun day for all with educational opportunities, food and music!
Our team is minimal, overwhelmed with things to do, and always struggling to find enough time to finish our work throughout the day. Want to help? Check out our Volunteer page! We have a minimum age of 15, and only take individuals interested in long-term volunteering, no skills required.
HorsePower for Kids & Animal Sanctuary is our favorite local farm and Petting zoo! They are a local non-profit farm and petting zoo where you will find a variety of animals, including some Dancing Goats! They offer fun, educational opportunities for children and adults to interact with and care for animals that have been rescued from a variety of situations. We highly recommend you visit them! For more information visit their website at HorsePower For Kids, or facebook page @HorsePowerforKids.

Introduction
the Atom JavaScript Frontend Framework
!!!
Please note the AjsDoc is the example application for the Ajs framework so it is available in offline mode too. It currently consumes about 6 megabytes of the indexed DB storage
for all (unoptimized) resources it is using so if you don't want to have these data stored in your browser you have to clean the application cache using developer tools.
AJS (pronounce /aɪs/) is JavaScript MVVM Single Page Application framework written in TypeScript focused to the rapid web browser application development, team role separation, offline
web applications and great user experience. It is developed with TypeScript (currently 2.2.1) with transpillation target ECMA5 (2015 and 2017 versions are focused and tested as well).
It is developed in order to support standard web browsers starting with IE10.
Ajs is provided with set of development tools focusing the Visual Studio (not Code, full one), currently in version 2015, support for VS 2017 is planned soon. This set of tools includes
project and item templates, WebApp packer simplifying and speeding up the development process, documentation generator and documentation viewer (the same one you are looking to now).
All tools are designed to add missing features for VS or make the development faster and easier. Also, setting up the development environment is easy and fast with this set of tools.
The Ajs Framework code is written in the C# way so classes and interfaces are split to separate files and the design of the code overall is similar to the C#. Also, the MVVM concept has
its inspiration in "Windows Forms" or the Borland "Delphi" concept (its probably more similiar to WPF as it is using separate language for template definition) except the data binding which
is not supported now. The view state is managed in the React way but it is extended about templating in separate HTML files instead of JSXs. Ofcourse, everything is adopted to the Web environment
so all the Web and Browser functionalities known to web users will stay the same.
Ajs currently does not support any "dependency" loader such as require.js so the dependency and initialization of 3rd party libraries must be done manually according the documentation. Of course,
other methods, like webpack, can be used to for the JavaScript single library package preparation.
Issues, changelog and project management of the Ajs Framework project can be found at GitHub
Until the Ajs Framework version 1.0.0 will be released the source code for complete set of tools including examples is managed in GitHub AjsDev
repository.

UNFORGIVEN
Review by John Beachem
* * * * *
Directed by: Clint Eastwood Written by: David Webb Peoples
In the town of Big Whisky, Wyoming, a prostitute has just been sliced up by two of her clients. After the local sheriff, Little Bill (Gene Hackman), makes the attackers pay only by giving the prostitute's employer some of their horses, her friends take matters into their own hands. They pool their money and place a bounty of one thousand dollars on the two cowboys, and send word out far and wide. William Munny (Clint Eastwood) used to be a known thief and murderer.  He's approached by The Schofield Kid (Jaimz Woolvet), a young gunfighter trying to make a name for himself. The kid proposes that he and Munny go to Big Whisky and collect on the bounty. Munny has no desire to return to his old ways, but he's failing as a farmer, and he needs the money. So Munny agrees on one condition, his old friend Ned Logan (Morgan Freeman) be allowed to join them. The three head for Big Whisky, The kid eager to make a name for himself, Munny and Logan haunted by ghosts from their murderous pasts.
There are some who will no doubt claim Clint Eastwood is biting the hand that fed him. They will say he is now slandering the genre that made him a star, and for that he should be crucified, stoned, hanged, or worse. I completely disagree. I don't believe "Unforgiven" is anti-western, I think Eastwood is simply showing a different face to the old west. Be forewarned, the face he's showing is a dark, depressing, and sadly realistic one. In fact, the entire movie is saturated by a sense of sadness. Watching the film on mute, you would still be able to feel the sense of emptiness Eastwood brilliantly conveys with his direction. Make no mistake, this isn't an action movie. It's a character study, and while the outstanding performances add a lot to the film's characters what really makes these people real is the way they are written. In David Peoples' ("Blade Runner") script, everyone is human. There are no superheroes nor villains, no one's perfect and no one's inhuman. Every character makes mistakes, everyone has a breaking point, and the sad fact of the matter is, there are no good guys. Oh sure, there are protagonists and antagonists, but you can understand everyone's motives and actions. In a strange sort of way, you won't want anyone to die, not even Little Bill. Yet you'll know, deep in your heart, that Bill Munny's words are true: "We all got it comin kid."
One of the best things about "Unforgiven" is the cast. While I'm obviously referring primarily to the three main cast members, Eastwood, Freeman, and Hackman, the entire supporting cast does a great job as well. To start with, we've got Eastwood, the king of westerns himself. Eastwood does an amazing job as a man trying to convince himself that he has changed his ways. The way he plays William Munny we think this character is really all his past characters (Josey Wales, the man with no name, even Dirty Harry) rolled up into one, trying to both atone for and forget the things he's done in the past. Then we have Morgan Freeman, playing a man too loyal and honest for his own good. Freeman brings remarkable depth and intelligence to every character he plays, and that has seldom been more true than it is here. Finally we have Gene Hackman, giving a performance the likes of which I've seldom seen. Hackman makes Little Bill into something much more than just another archetypal western villain. Little Bill is already written as having a sort of twisted sense of justice, and a dream to do nothing more than work on his house (this provides some of the film's few comic moments), but Hackman imbues the character with something more. It's hard to describe, and I know I can't do it justice here. This performance actually has to be witnessed to be appreciated.
You're no doubt wondering if there's any action in the movie. Yes there is, but not in the traditional sense. One of the things that most impressed me about "Unforgiven" was the way in which Eastwood could film excellent action scenes without glamorizing them. In fact, quite the opposite approach was taken. For example, there's a scene in which Munny shoots a man from some distance off with a shotgun. The hapless fellow crawls behind a rock, trailing blood behind him while his friends take cover. There's no pulse pounding music here, no war cries from the combatants, only the victim crying for water. Finally Eastwood shakes his head sadly and yells out at the man's friends, "Will you give him a drink of water for Christ's sake?! We ain't gonna shoot!" Even the giant, climactic shoot out at film's end is like this (oh come on, you knew there was going to be one). There's nothing glorious about the killing, each character simply does what they feel they have to do. It's a remarkable achievement by Eastwood, being able to film the movie in such a way, and a lot of it has to do with his use of the score, by composer and longtime Eastwood collaborator Lennie Niehaus. The score is haunting and powerful, but never lively or upbeat. I know that sounds bad, but it's remarkably effective. If a loud, uplifting score had been written for the gun fights it would have taken something away from them. By keeping the music low, or even completely unused during the fights, Eastwood makes them much more realistic and saddening.
When I first saw "Unforgiven" back in '92, I dismissed it as a good, if overrated, western about growing old. I saw it again about two years later and dismissed it again, but decided it wasn't about growing old, it was about vengeance and not being able to escape ones past. I watched it for the third time about a month ago, and I'm still haunted by it. There's something powerful and moving about this film that, try as I might, I can't put my finger on. It manages to interweave not only the two story arcs I described above, but dozens more into a film that has a rightful place on my personal 100 best of all time list. Those who shove the film away as just another western, or try to place a similar restrictive title on it do so at their own risk. Don't take this movie lightly, and don't ignore it or you're doing yourself a great disservice. I know it seems like a long film, running 131 minutes, but I was so involved I didn't even notice the time going by. I'd recommend "Unforgiven" to everyone, whether you like westerns or not, and give it a full five out of five stars.

Domino, Extlib, GRUNT, JSON and Yeoman
TL:TR
With a few tweaks and clever setup, you can have web developers deliver front-ends for Domino without ever touching it.Contemporary web development workflows separate front-end and back-end through a JSON API and HTTP (that's 21st century 3270 for you). The approach in these workflows is to treat the webserver as source of static files (HTML, CSS, JS) and JSON payload data being shuffled back and forth. This article describes how my development setup makes all this work with Domino and Domino designer.
The full monty
The front-end tools I use are:- Node.js: a JavaScript runtime based on Google's V8 engine. It provides all runtime for all the other tools. If you don't have a node.js installation on your developer workstation, where were you hiding the last 2 years?
- Bower: a dependency manager for browser files like CSS, JS with their various frameworks. You add a depencency (e.g. Bootstrap) to the
bower.json
file and Bower will find the right version for you - Grunt: a task runner application, used for assembly of web sites/applications (or any other stuff). Configured using a
Gruntfile.js
: it can do all sorts of steps like: copy files, combine and minify, check code quality, run tests etc. - Yeoman: A application scaffolding tool. It puts all the tools and needed configurations together. It uses generators to blueprint different applications from classic web, to reveal application to mobile hybrid apps. The site lists hundreds of generators and you are invited to modifiy them or roll your own
- GIT: the version control system
My general directory layout starts with a project folder that has entries for code, documentation, nsf and a misc. folder. I only put the
code
folder into the GIT version control.
The front-end developer doesn't need any of the Domino components available to create user interface and interaction models. The back-end developer will use exclusively the REST controls from the Domino XPages Extension library (which is part of a default current Domino server install). The two directory structures are linked in a GIT project, but that isn't mandatory. One step that made my live much easier: take the
dist
directory and link it to WebContent
. This saves me the step to copy things around. The fine-tuning of the setup is where the fun starts.But first things first:
Installation
You follow the Node.js instructions for your platform to get a running node.js version (v4.2.1 as time of writing). Thereafter you install as admin (sudo
for Linux/Mac) Bower, Grunt and Yeoman:
npm install -g bower
npm install -g grunt-cli
npm install -g yo
npm install -g generator-karma generator-angular
I use the generator-angular, but looking very promising is mcfly. Go and checkout the Yeoman website for the many more options you have for generators.
Change to the Frontend directory and initialize your new front-end application using
yo angular myAwesomeApp
You get walked through a series of questions, node.js does some magic (requires internet connection) and you have a basic Angular.js application ready. There are tons of tutorials how to use Yeoman, Bower, Grunt and Angular.js, so go google them, I'll limit myself to the tweaks I made to make my Domino live easier.
Once the
yo
magic work concludes, you can use
grunt serve
to have a first look at your new frontend in action (by default on port 9000). As long as that grunt task is running, any change you save will automatically reload the browser and show you the new result (praise to the second monitor).
Tweaks
- All my JSON controls live on an XPage with the name
api.xsp
.
I create a directory under the app directory named api.xsp and add one file each that matches the path property in the XPages REST controls (api.xsp/people, api.xsp/setup.json etc). These files contain sample JSON of what the Domino REST control eventually will return. - To prevent that directory to be copied into the NSF (when
grunt build
runs), I edit theGruntfile.js
and change the copy:dist:files:src array to include'!api.xsp'
.
If you use more XPages you could use a wildcard. Be careful to include the exclamation mark which stands for not - With the file open, I adjust the clean section where I add
'!<%= yeoman.dist %>/WEB-INF{,*/}*'
toclean:dist:files:src
.
Again don't forget the exclamation mark. This allows me to keep WebContent and dist linked and the build task won't wipe out the WEB-INF directory.
Now we can make JSON calls (in Angular services/providers) to our REST endpoints without having anything Domino installed (which allows you to use a Mac or Linux for this part of the exercise). The only missing step: posting things back. - This part is
a little trickiereasy when you ask the right people:
in a frontend dev environment you don't want to fully simulate the server, a static reply or just echo the submitted JSON does suffice.
The default configuration of the Gruntfile.js only caters to GET requests, but I wasn't the first to ask, so there's precedence. It turned out, that it is just a few lines of changes at the top of your Gruntfile.js (and 2 lines down):var bodyParser = require("body-parser"); var postResponder = function(request, response, next) { if (request.method === 'POST') { console.log(request.method+" "+request.url); response.setHeader('Content-Type', 'application/json'); response.statusCode = 200; response.end(JSON.stringify(request.body)); } else { next(); } };
and to theconnect.livereload.options.middleware
object:
function (connect) { return [ connect().use('/api.xsp', bodyParser.json()), connect().use('/api.xsp', postResponder), connect.static('.tmp'), connect().use('/bower_components', connect.static('./bower_components')), connect().use('/app/styles', connect.static('./app/styles')), connect.static(appConfig.app) ]; }
Note: You only add the first two lines after the return statement, the others are already there.
As usual YMMV!

2012 National Geographic Photography Contest Winners
Paula Nelson • Original article
As a leader in capturing the world through brilliant imagery, National Geographic sets the standard for photographic excellence. This year’s competition brought 22,000 entries from over 150 countries, professionals and amateurs participating. Photographs were submitted in three categories: people, places and nature; and entries judged on creativity and photographic quality by a panel of experts. There was a Grand Prize winner , a winner in each category and a collection of Viewer’s Choice Winners as well.
The Explosion!
Grand Prize Winner and 1st Place/Nature: The subject’s name is Busaba, a well cared for Indochinese Tigress whose home is at Khao Kheow Open Zoo, Thailand. I had taken many portraits of Busaba previously and it was becoming more and more difficult to come up with an image that appeared any different to the others. Which is why I took to observing her more carefully during my visits in the hope of capturing something of a behavioral shot. The opportunity finally presented itself while watching Busaba enjoying her private pool then shaking herself dry. In all humility I have to say that Mother Nature smiled favorably on me that day!

The Matterhorn
1st Place/Places: The Matterhorn, 4478 meters at full moon. (Photo and caption by Nenad Saljic/National Geographic Photo Contest)
Amongst the Scavengers
1st Place/People: At the end of the day women are allowed to pick through the dumpsite. (Photo and caption by Micah Albert/National Geographic Photo Contest)
Iceberg Hunters
Viewer’s Choice/Places: Chipping ice off an iceberg is a common way for the Inuit community to retrieve fresh drinking water while on the land. During a weekend long hunting trip, we came upon this majestic iceberg frozen in place. It was a perfect opportunity to grab enough ice and drinking water for the remainder of the trip. (Photo and caption by Adam Coish/National Geographic Photo Contest)
Expedition Amundsen
Viewer’s Choice/People: A race that follows in the path of the famous explorer Roald Amundsen brings the contestants to the Hardangervidda Mountainplateu, Norway. 100km across the plateau, the exact same route Amundsen used to prepare for his South Pole expedition in 1911 is still used by explorers today. Amundsen did not manage to cross the plateau and had to turn back because of bad weather. He allegedly said that the attempt to cross Hardangervidda was just as dangerous and hard as the conquering of the South Pole. (Photo and caption by Kai-Otto Melau/National Geographic Photo Contest)
Tender Moment
Viewer’s Choice/Nature: Everyday in Mara starts with something new and different and day ends with memorable experiences with spectacular photographs. I was very lucky sighting and photographing Malaika - the name of female Cheetah and her cub. She is well known for its habit to jump on vehicles. She learned that from her mother Kike, and Kike from her mother, Amber. Like her mother she is teaching lessons to her cub. Teaching lessons means the addition of another moment for tourists. This is one of the tender moments between Malaika and her cub. I was very lucky to capture that moment. (Photo and caption by Sanjeev Bhor/National Geographic Photo Contest)
Red Fox Catching Mouse Under Snow
Honorable Mention: With his exceptional hearing, a red fox has targeted a mouse hidden under 2 feet of crusted snow. Springing high in the air he breaks through the crusted spring snow with his nose and his body is completely vertical as he grabs the mouse under the snow. (Photo and caption by Micheal Eastman/National Geographic Photo Contest)
Chinese Traditional Dragon Boat Racing
Honorable Mention: Dragon boating is a Chinese traditional entertainment. As an aquatic sport to memorize Qu Yuan, a patriotic poet in ancient china, it is usually held in festivals, which can be traced back to two thousand years ago. (Photo and caption by 关嘉城/National Geographic Photo Contest)
East Of Iceland
Honorable Mention: Glacial ice washes ashore after calving off the Brei amerkurjˆkull glacier, on Iceland’s eastern coast. During the waning light of summer this image was created over the course of a 4-minute exposure while the photographer backlit the grounded glacial ice with a headlamp for 2 of those 4 minutes. (Photo and caption by Eric Guth/National Geographic Photo Contest)
Captive
Honorable Mention: Yayasan Galuh Rehabilitation Center is and impoverished mental health facility based in Bekasi, Indonesia that hosts over 250 patients. Most come from poor families no longer interested in managing their condition, or are unable. Some patients are homeless, deposited after being taken off streets by police. The only medical treatment received is for skin conditions. No assessments, psychotherapy or psychiatric medications is available. Over one third of the patients are shackled in chains. These measures are implemented to those thought to be violent, uncontrollable and dangerous. (Photo and caption by Wendell Phillips/National Geographic Photo Contest)
Eerie eiffel
Honorable Mention: The winter gloomy day worked to my advantage to create this eerie feeling of the famous landmark Eiffel tower. (Photo and caption by Indra Swari Wonowidjojo/National Geographic Photo Contest)
Predation Up Close and Personal
Honorable Mention: I was surrounded by thousands of fish that moved in synchrony because of the predation that was happening. It was an incredible experience. (Photo and caption by Fransisca Harlijanto/National Geographic Photo Contest)
Ursus Arctos Horribilis
Honorable Mention: This photo of a wild, Alaskan, brown bear digging on a game trail was taken with a home made motion controlled triggering device hooked up to my DSLR. (Photo and caption by Jason Ching/National Geographic Photo Contest)
Stilt Fishing
Honorable Mention: Stilt fishing is a typical fishing technique only seen in Sri Lanka. The fishermen sit on a cross bar called a petta, tied to a vertical pole planted into the coral reef. This long exposure shot shows how unstable their position is. (Photo and caption by Ulrich Lambert/National Geographic Photo Contest)


BOUNCE A film review by James Brundage Copyright 2000 filmcritic.com filmcritic.com
Great. Here I am, writing a review of yet another cheesy, clichéd, Ben Affleck romantic comedy in which I will probably be flamed by Affleck fans, Paltrow fans, romantics, teens, and widows. Yeah… widows. Why? Because Bounce is the latest in a string of contrived romantic comedies to feature a man falling for a widow whom he helped to make a widow.
Yeah… it's our old friends Bob and Harvey Weinstein, and this time they're capitalizing on plane crashes, public relations companies, alcoholics, and stalkers all in the same wicked stroke. Here we have Buddy Amaral (Affleck), just a good-old sweet talking ad rep who happens to give a free first class plane ticket to a guy named Greg (Tony Goldwyn) in order to sleep with Mimi (Natasha Henstridge… really, who wouldn't go for that)? Of course, the plane crashes, and, wouldn't you know it, he happens to rep the airlines. So he does what any person would: He drinks.
Cut to a year later, and Buddy's out of rehab and decides to take Step 8 (Contact those you have wronged and make amends) a little too seriously, and he begins following the widowed Abby (Gwyneth Paltrow), the former wife of Greg. Finding out that she's a realtor, he fixes it so he rips his own business off to the tune of $100,000, making herself a double commission to boot. Grateful as she is, she buys a couple of Dodgers tickets and the two head down the eventless path towards true bliss.
If this plot thrills you, or makes you coo, "Ah, how sweet," then please go see Bounce. Now. I'm sure you'll enjoy the paint-by-numbers romance. But let's face it, this is not exactly a great flick. In fact, it's downright terrible. In fact, the idea of being romanced by an alcoholic stalker named Buddy is a little more Silence of the Lambs than Sliding Doors. Writer-director Don Roos's last project, The Opposite of Sex, was one of the most honest films about homosexual stereotypes in recent years. And I'll give him the benefit of the doubt that he was trying to address issues of honesty and grieving, but this time he crashes and burns like the plush 747 O'Hare red-eye that makes a fiery farewell.
The performances are weak, the script couldn't hold up a toddler, and the emotional value is slightly above that of a couple of Valium. Sorry, Gwen and Ben, but even that oh-so-cute non-romance we read about at checkout lines daily can't salvage this wreck.

Jordan foils plot against U.S., Israeli diplomats and American soldiers: newspaper
AMMAN (Reuters) - Jordanian intelligence recently foiled a plot by two suspected militants to mount terror attacks against U.S. and Israeli diplomats alongside U.S. troops deployed at a military base in the south of the country, state-owned al-Rai newspaper reported on Tuesday.
It said the suspects had planned to drive vehicles into their targets and attack them with firearms and knives. They would stand trial in Jordan’s state security court, it added.
Militants from Islamic State and other radical jihadist groups have long targeted the U.S.-allied kingdom and dozens of militants are currently serving lengthy prison terms.
King Abdullah, a Middle East ally of Western powers against Islamist militancy, has been among the most vocal leaders in the region in warning of threats posed by radical groups.
Several incidents over the past few years have jolted the Arab kingdom, which has been comparatively unscathed by the uprisings, civil wars and Islamist militancy that have swept the Middle East since 2011.
Jordan said last year it had foiled an Islamic State plot that included plans for a series of attacks on security installations, shopping malls and moderate religious figures. It arrested the suspects.

| Class | Cri::OptionParser |
| In: |
lib/cri/option_parser.rb
|
| Parent: | Object |
Cri::OptionParser is used for parsing commandline options.
Option definitions are hashes with the keys `:short`, `:long` and `:argument` (optionally `:description` but this is not used by the option parser, only by the help generator). `:short` is the short, one-character option, without the `-` prefix. `:long` is the long, multi-character option, without the `—` prefix. `:argument` can be :required (if an argument should be provided to the option), :optional (if an argument may be provided) or :forbidden (if an argument should not be provided).
A sample array of definition hashes could look like this:
[ { :short => 'a', :long => 'all', :argument => :forbidden }, { :short => 'p', :long => 'port', :argument => :required }, ]
For example, the following commandline options (which should not be passed as a string, but as an array of strings):
foo -xyz -a hiss -s -m please --level 50 --father=ani -n luke squeak
with the following option definitions:
[ { :short => 'x', :long => 'xxx', :argument => :forbidden }, { :short => 'y', :long => 'yyy', :argument => :forbidden }, { :short => 'z', :long => 'zzz', :argument => :forbidden }, { :short => 'a', :long => 'all', :argument => :forbidden }, { :short => 's', :long => 'stuff', :argument => :optional }, { :short => 'm', :long => 'more', :argument => :optional }, { :short => 'l', :long => 'level', :argument => :required }, { :short => 'f', :long => 'father', :argument => :required }, { :short => 'n', :long => 'name', :argument => :required } ]
will be translated into:
{ :arguments => [ 'foo', 'hiss', 'squeak' ], :options => { :xxx => true, :yyy => true, :zzz => true, :all => true, :stuff => true, :more => 'please', :level => '50', :father => 'ani', :name => 'luke' } }
| delegate | [RW] |
The delegate to which events will be sent. The following methods will be
send to the delegate:
@return [option_added, argument_added] The delegate |
| options | [R] |
The options that have already been parsed.
If the parser was stopped before it finished, this will not contain all options and `unprocessed_arguments_and_options` will contain what is left to be processed. @return [Hash] The already parsed options. |
| raw_arguments | [R] |
@return [Array] The arguments that
have already been parsed, including
the -- separator. |
| unprocessed_arguments_and_options | [R] |
The options and arguments that have
not yet been processed. If the parser wasn’t stopped (using {stop}), this list will be empty.
@return [Array] The not yet parsed options and arguments. |
Parses the commandline arguments. See the instance `parse` method for details.
@param [Array<String>] arguments_and_options An array containing the
commandline arguments (will probably be `ARGS` for a root command)
@param [Array<Hash>] definitions An array of option definitions
@return [Cri::OptionParser] The option parser self
Parses the commandline arguments into options and arguments.
During parsing, two errors can be raised:
@raise IllegalOptionError if an unrecognised option was encountered,
i.e. an option that is not present in the list of option definitions
@raise OptionRequiresAnArgumentError if an option was found that did not
have a value, even though this value was required.
@return [Cri::OptionParser] The option parser self


search
Places API entrypoint. The Search Entrypoint returns POIs and addresses matching the user's query, taking into account the user's location context. For more information on possible parameters and options regarding this entrypoint visit Search Entrypoint Places API documentation.

A URL field pre-filled with a ‘http://’ which doesn’t disappear on focus is a terrible UI convention.
No one types out URLs so contrary to its intended purpose it adds time to completing the field because you have to delete the existing http:// before pasting in your own already http:// prefixed URL.


Add a search
Search is a core feature of the Splunk App Framework. All of the framework UI controls can be bound to a search in various ways. Some controls are populated by searches, some modify the searches they are bound to, and some do both.
Each search is represented by a search context, which manages the query, properties, operation, and lifetime of an individual search job. You can create search contexts using Django template tags or JavaScript. Search contexts can correspond to a saved search, or a search job you create on the fly in code or dynamically with UI controls.
Creating a search context
A search context can be input dynamically using a SearchBar control or hardcoded into a framework app.

CollectionBin
public struct CollectionBin<Backstorage> : Collection where Backstorage : RangeReplaceableCollection
Represents a Facade for RangeReplaceableCollection
that is a Collection
itself
Provides updating
method to find
the element if it exists and update
or remove
it
based on the rules provided by CollectionFilter<Element>
If Backstorage
doesn’t contain the element and the element complies to the rules, updating
method
will append the element
Every call of updating
method returns BinUpdateResult<CollectionBin>
that contains info about
the update operation
CollectionBin
can be initialized with filter and sorting closures specifying the rules how to treat the elements.
Example
//let's have a model like
struct CollectionTestObjectMock: Hashable, Equatable {
var value: String
var status: ObjectStatus
var rank: Int
func hash(into hasher: inout Hasher) {
hasher.combine(value)
hasher.combine(rank)
}
// -Note: since value and rank are a part of unique value of the object the only part that
// cab be changed is the status
static func == (lhs: CollectionTestObjectMock, rhs: CollectionTestObjectMock) -> Bool {
lhs.status == rhs.status
}
}
Then a basic initizlization will be:
//Will contain object with status == .cold and sorted by rank descending
DiffCollectionFilter<CollectionTestObjectMock>(name: "Status is new or old",
filter: { $0.status == .cold},
sort: { $0.rank > $1.rank })

public init(collection: Backstorage, filter: CollectionFilter<Element>? = nil, sort: CollectionSort<Element>? = nil)
Parameters
collection
Any
RangeReplaceableCollection
filter
Provides rules to insert/delete/update elements
sort
Provides sorting rules for injecting elements.
-
Returns the position immediately after the given index.
The successor of an index must be well defined. For an index
i
into a collectionc
, callingc.index(after: i)
returns the same index every time.Parameters
i
A valid index of the collection.
i
must be less thanendIndex
.Return Value
The index value immediately after
i
. -
Accesses the element specified by an Index.
let names = CollectionBin(["Adams", "Bryant", "Channing", "Douglas", "Evarts"]) let name = streets[2] print(streetsSlice) // "Channing"
Complexity
O(1)
Parameters
Index
A index of the element. The index must be valid.
-
The core function of this struct.
Usage Example:
//let's have a model like struct CollectionTestObjectMock: Hashable, Equatable { let value: String let status: ObjectStatus let rank: Int }
Then the call of the function might look like:
let newElement = CollectionTestObjectMock(value: "TEST", status: .new, rank: 150) let result = source.updating(newElement, whereUnique: { $0.value == "TEST" }, whereCompare: { $0.status == .new })
NOTE: The method will try to look for an element with “TEST” value.
- if the element exist then based on compare closure it will update an element or will do noting
- if the element exist but doest pass filter function of the Bin, the element will be removed
Declaration
Swift
public func updating(_ element: Element, whereUnique unique: CollectionFilter<Element>, whereCompare compare: CollectionFilter<Element>) -> BinUpdateResult<CollectionBin>
Parameters
element
Element
unique
CollectionFilter
closure that defines the uniqueness of the element compare
CollectionFilter
closure that defines the changes of the element Return Value
-
Recreates a new
CollectionBin
using the same Filter and Sorting but new collection of elelemtsDeclaration
Swift
public func updating(with elements: Backstorage) -> CollectionBin
Parameters
elements
Collection of elements of type
Backstorage
Return Value
CollectionBin
-
The core function of this struct.
Note:
- Hash value is used to idenfy the unique element
- Conformance to
Equatable
is used to identify if an element has changed or not
Usage Example:
//let's have a model like struct CollectionTestObjectMock: Hashable, Equatable { var value: String var status: ObjectStatus var rank: Int func hash(into hasher: inout Hasher) { hasher.combine(value) hasher.combine(rank) } // -Note: since value and rank are a part of unique value of the object the only part that // cab be changed is the status static func == (lhs: CollectionTestObjectMock, rhs: CollectionTestObjectMock) -> Bool { lhs.status == rhs.status } }
Then the call of the function might look like:
let newElement = CollectionTestObjectMock(value: "TEST", status: .new, rank: 150) let result = source.updating(newElement)
NOTE: The method will try to look for an element with “TEST” value and rank 150 (since they participate in hash value)
- if the element exists then based on Hash value it will update an element or will do noting
- if the element exists but doest pass filter function of the Bin, the element will be removed
- if the element exists, passed filter function but not equal to existed one, it will be updated, otherwise no operation is performed
Declaration
Swift
func updating(_ element: Element) -> BinUpdateResult<CollectionBin>
Parameters
element
Element as
Hashable
andEquatable
Return Value
-
Provides convenient description for debug purposes
Declaration
Swift
public var description: String { get }
