Chart Scripting to change Gantt Chart Task Label

[ctan1010]

Hi,

I would like to use chart scripting to dynamically change the color of "Task Label" within Gantt Chart - Value (Y) Series.

I've been experimenting but could not find the appropriate function to call during onRender.

I've tried beforeDrawSeries() and beforeDrawSeriesTitle() but have not been able to locate "Task Label" within these functions.

Would appreciate your assistance.


Thank you.
Calvin

Hi Calvin,

On the series, it is the Decoration Label you are looking for. Below is a piece of code that will change those label colors, and attached is an example created in BIRT 2.5.1

function beforeDrawSeries( series, isr, icsc ) {
	importPackage(Packages.org.eclipse.birt.chart.model.attribute.impl);
	if (series.eClass().getName().equals("GanttSeries"))
	{
		java.lang.System.out.println(series);
		series.getDecorationLabel().setBackground(ColorDefinitionImpl.BLACK());
	}
}

Hi vdodson,

Thank you for your examples.
However, I neglected to mention that I'm on Eclipse 3.4.1.

Unfortunately, getDecoration is not available on series on this version.

Any other thoughts ?
