Chart Script example of modifying series entries in the legend

JasonW

This example uses a scripted dataset to get the names of each series for the legend. A hidden table is placed on the report that calls the dataset. The oncreate for the row sets persistent global variables with the names of the series.

 var st1 = this.getRowData().getColumnValue("series1");
var st2 = this.getRowData().getColumnValue("series2");
var st3 = this.getRowData().getColumnValue("series3");
reportContext.setPersistentGlobalVariable("seriestitle1", st1);
reportContext.setPersistentGlobalVariable("seriestitle2", st2);
reportContext.setPersistentGlobalVariable("seriestitle3", st3);

<br />
The chart series titles are set to<br />
<br />
series1-title, series2-title, and series3-title in the third tab of the chart wizard.<br />
<br />
Then in the chart script beforeDrawLegenItem the series titles are changed based on the value retrieved from the scripted dataset.

function beforeDrawLegendItem(lerh, bounds, icsc)
{
 if( lerh.getLabel().getCaption().getValue().compareToIgnoreCase("series1-title") == 0 ){
     var myst3 = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("seriestitle1");
  lerh.getLabel().getCaption().setValue(myst3);
 }
 if( lerh.getLabel().getCaption().getValue().compareToIgnoreCase("series2-title") == 0 ){
     var myst3 = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("seriestitle2");
  lerh.getLabel().getCaption().setValue(myst3);
 }
 if( lerh.getLabel().getCaption().getValue().compareToIgnoreCase("series3-title") == 0 ){
     var myst3 = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("seriestitle3");
  lerh.getLabel().getCaption().setValue(myst3);
 }
}
