Hi,<br />
<br />
Calculate Percentage and append its value to the legend. you can write script for it on render function of chart.<br />
<br />
Refer given report script. Legends are appended with "XX".<br />
<br />
Hope it will help you.<br />

Thank you very much for your feedback. This is the code to drawLegend
function beforeDrawLegendItem( lerh, bounds, icsc )
{
//lerh.getLabel().getCaption().setValue("xx");
var x = lerh.getLabel().getCaption().getValue();
lerh.getLabel().getCaption().setValue(x + "xx");
//icsc.getChartInstance().getLegend().setText("****");
}
How can I calculate % value for the item on the graph when it runs this method? How can I add Total 100% Lengend Item in the legend?
Thanks and regards
