Hi,

I'm trying to update series name (not legend items: in attached image below i want replace "Series 1" by a runtime value) in a barchart with javascript. I tried beforeDrawSeries event but my code has no effect:

function beforeDrawSeries( series, isr, icsc )
{	series.getLabel().getCaption().setValue('My serie name');
//logInfo('beforedrawseries is fired', icsc);
}

I also tried beforeDrawSeriesTitle but that event seems never firing.

function beforeDrawSeriesTitle( series, label, icsc )
{	label.getCaption().setValue('My serie name');
//	logInfo('beforeDrawSeriesTitle is never fired', icsc);	
}

Please could someone help

The beforeDrawSeriesTitle is only called for charts without axes. What
are you trying to change in the output of the chart? You can set the
series identifier like:

function beforeGeneration( chart, icsc )
{
importPackage(Packages.java.util);
importPackage(Packages.org.eclipse.birt.chart.model.data.impl);
importPackage(Packages.org.eclipse.birt.chart.model.component.impl);
importPackage(Packages.org.eclipse.birt.chart.model.type.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);

var xAxis = chart.getAxes().get(0);
var yAxis = xAxis.getAssociatedAxes().get(0);
var xSerieDef = xAxis.getSeriesDefinitions().get(0);
var ySerieDef1 = yAxis.getSeriesDefinitions().get(0);

ySerieDef1.getSeries().get(0).setSeriesIdentifier("My Series 1");

}

Thank you for your reponse Jason.

I set up series label to display "value series name" option, just above each bar. So i'm trying to update this series name to replace it by its parameter value.

I tried your code in the attached report and it works, but labels above each bar chart keep using the old series name :/ Very strange. Are these labels generated before the "beforeGeneration" event?

If you change the code a bit and move it to the beforeDataSetFilled
script it should work:

function beforeDataSetFilled( series, idsp, icsc )
{
var chart = icsc.getChartInstance();

importPackage(Packages.java.util);
importPackage(Packages.org.eclipse.birt.chart.model.data.impl);
importPackage(Packages.org.eclipse.birt.chart.model.component.impl);
importPackage(Packages.org.eclipse.birt.chart.model.type.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);

var xAxis = chart.getAxes().get(0);
var yAxis = xAxis.getAssociatedAxes().get(0);
var xSerieDef = xAxis.getSeriesDefinitions().get(0);
var ySerieDef1 = yAxis.getSeriesDefinitions().get(0);

//logInfo(ySerieDef1.getSeries().get(0).getSeriesIdentifier(), icsc)
ySerieDef1.getSeries().get(0).setSeriesIdentifier("My new series name");

}

or leave it where it is and add:

runSeries = ySerieDef1.getRunTimeSeries();
firstRunSeries = runSeries.get(0);
firstRunSeries.setSeriesIdentifier("My new series name");
