Hello,
I have been using an onRender function to set the colors for the bars and legend in a chart. I have some reports that contain a large number of charts. I want to know if there is a way to set the colors in one location and reference that in each chart or if I need to continue to update the script in each chart's onRender script in the report individually.
Thanks,
Example function:
function beforeDrawDataPoint( dph, fill, icsc ) {
var ConditionX = dph.getSeriesDisplayValue();
if(ConditionX.contains("Expo Invitation")) { fill.set(255, 255, 0); }
elseif(ConditionX.contains("Other")) { fill.set(211, 211, 211); }
else if(ConditionX.equals("Survey")) { fill.set(50, 205, 50); }
else if(ConditionX.contains("No Survey")) { fill.set(255, 165, 0); }
}
function beforeDrawLegendItem( lerh, bounds, icsc ){
var Condition = lerh.getLabel().getCaption().getValue();
if(Condition.contains("Expo Invitation")) {lerh.getFill().set(255, 255, 0); }
else if(Condition.contains("Other")) {lerh.getFill().set(211, 211, 211); }
else if(Condition.equals("Survey")) {lerh.getFill().set(50, 205, 50); }
else if(Condition.contains("No Survey")) {lerh.getFill().set(255, 165, 0); }
}

Hi,
I think this would be a typical case requiring a java event handler. It's a little bit trickier to setup than javascript handlers, but very helpful if you have many charts sharing the same rules.
Alternatively you could create a java helper class implementing conditional rules, and then invoke this class from javascript handlers. Thus colors and conditions would not be hard-coded in each chart, and you could still use javascript to add some other specific rules in charts. For example:
ImportPackage(Packages.test.mycustombirtchartpackage);
function beforeDrawDataPoint( dph, fill, icsc ) {
MyChartHelperClass.doConditionalFormat(fill, dph.getSeriesDisplayValue());
}
function beforeDrawLegendItem( lerh, bounds, icsc ){
MyChartHelperClass.doConditionalFormat(lerh.getFill(), lerh.getLabel().getCaption().getValue());
}
