Hi,
I want to change the label of a marker in a chart via script. I use
beforeDrawMarkerLine function (see below). The following (setLabel) does
not work (this error:
Can't find method
org.eclipse.birt.chart.model.component.impl.MarkerLineImpl.s etLabel(string).
at line 19 of chart script:'')
Perhaps anybody can give me a hint. thanks.
function beforeDrawMarkerLine(axis, markerLine, icsc)
{
importPackage( Packages.org.eclipse.birt.chart.model.data.impl );
var min_value =
icsc.getExternalContext().getScriptable().getPersistentGloba lVariable( "min_val");
markerLine.setValue(NumberDataElementImpl.create(min_value)) ;
markerLine.setLabel("Value: " + min_value);
}

Jason,
setting the line works fine, it just does not set the label of the line.
My script now looks like this, but the error remains.
function beforeDrawMarkerLine(axis, markerLine, icsc)
{
importPackage(Packages.org.eclipse.birt.chart.model.data.imp l);
importPackage(Packages.org.eclipse.birt.chart.model.componen t.impl);
var min_value =
icsc.getExternalContext().getScriptable().getPersistentGloba lVariable( "min_val");
markerLine.setValue(NumberDataElementImpl.create(min_value)) ;
// works fine so far
// this does not work
markerLine.setLabel("This is the line");
}

Try:
markerLine.getLabel().getCaption().setValue("Test");
