Description David Paquin CLA 2011-09-08 11:51:27 EDT 
The current implementation of the bar chart allows users to create a stacked chart, where each stack is a single series. It would be useful for my application (and I would assume some others) to be able to stack each y grouping. See http://www.birt-exchange.org/org/forum/index.php/topic/23355-any-way-to-stack-by-y-series-groupings/ for a full description.

in the bird exchange,the administrator BIRT Guru provide the Solution for the issue below:
------------------------------------------------------------------------------

Try something like this to actually change the series identifier:
 
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 numSeries = yAxis.getSeriesDefinitions().size();var i=0;while (i < numSeries){var ySerieDef = yAxis.getSeriesDefinitions().get(i);i++; ySerieDef.getSeries().get(0).setSeriesIdentifier("My Series " + i.toString());}}
 
This will change the legend in the label. The code above will change them to My Series 1, My Series 2, etc... You'll just have to replace that with your way to name them what you want. 

Hope this helps.
