/** |
|
* Class: $.jqplot.FunnelRenderer |
|
* Plugin renderer to draw a funnel chart. |
|
* x values, if present, will be used as labels. |
|
* y values give area size. |
|
* |
|
* Funnel charts will draw a single series |
|
* only. |
|
* |
|
* To use this renderer, you need to include the |
|
* funnel renderer plugin, for example: |
|
* |
|
* > <script type="text/javascript" src="plugins/jqplot.funnelRenderer.js"></script> |
|
* |
|
* Properties described here are passed into the $.jqplot function |
|
* as options on the series renderer. For example: |
|
* |
|
* > plot2 = $.jqplot('chart2', [s1, s2], { |
|
* > seriesDefaults: { |
|
* > renderer:$.jqplot.FunnelRenderer, |
|
* > rendererOptions:{ |
|
* > sectionMargin: 12, |
|
* > widthRatio: 0.3 |
|
* > } |
|
* > } |
|
* > }); |
|
* |
|
* IMPORTANT |
|
* |
|
* *The funnel renderer will reorder data in descending order* so the largest value in |
|
* the data set is first and displayed on top of the funnel. Data will then |
|
* be displayed in descending order down the funnel. The area of each funnel |
|
* section will correspond to the value of each data point relative to the sum |
|
* of all values. That is section area is proportional to section value divided by |
|
* sum of all section values. |
|
* |
|
* If your data is not in descending order when passed into the plot, *it will be |
|
* reordered* when stored in the series.data property. A copy of the unordered |
|
* data is kept in the series._unorderedData property. |
|
* |
|
* A funnel plot will trigger events on the plot target |
|
* according to user interaction. All events return the event object, |
|
* the series index, the point (section) index, and the point data for |
|
* the appropriate section. *Note* the point index will referr to the ordered |
|
* data, not the original unordered data. |
|
* |
|
* 'jqplotDataMouseOver' - triggered when mousing over a section. |
|
* 'jqplotDataHighlight' - triggered the first time user mouses over a section, |
|
* if highlighting is enabled. |
|
* 'jqplotDataUnhighlight' - triggered when a user moves the mouse out of |
|
* a highlighted section. |
|
* 'jqplotDataClick' - triggered when the user clicks on a section. |
|
* 'jqplotDataRightClick' - tiggered when the user right clicks on a section if |
|
* the "captureRightClick" option is set to true on the plot. |
