Can you use the beforeDrawAxisTitle script?
function beforeDrawAxisTitle(axis, title, scriptContext)
{
importPackage(Packages.org.eclipse.birt.chart.model.attribut e);
if (axis.getType() == AxisType.LINEAR_LITERAL)
{
title.getCaption( ).setValue( "Y-Axis Title By JavaScript");
title.getCaption( ).getColor( ).set( 32, 168, 255 );
}
}
You could also use the beforeGeneration like:
function beforeGeneration(chart, icsc)
{
cxtitle =
icsc.getExternalContext().getScriptable().getParameterValue( "chartTitle");
xAxis = chart.getBaseAxes()[0];
xAxis.getTitle().getCaption().setValue( cxtitle );
}
The above example sets the title based on a report parameter. This line
icsc.getExternalContext().getScriptable() gets the reportContext, which
can be used to get report parameters, persisted global variables and
session values.
