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.

Hi Calvin,<br />
<br />
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<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
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());
}
}
</pre>
