Color BIRT Chart manipulation

sairag

My graph is binded to one dataset and I am using the following script in the on render, after data set filled to fix the axis details :
=============================================================================
importPackage( Packages.java.util );
importPackage( Packages.org.eclipse.birt.chart.model.type.impl );

importPackage(Packages.org.eclipse.birt.chart.model.component.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);

function afterDataSetFilled(series, dataSet, icsc)
{

if( series.getClass() == BarSeriesImpl ){
var list = dataSet.getValues();

var X= parseInt(icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("X"));
var Y= parseInt(icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("Y"));
var Z= parseInt(icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("Z"));

var narray1 = new ArrayList( );

narray1.add(X);
narray1.add(Y);
narray1.add(Z);

dataSet.setValues(narray1);
}else{
var catArray = new ArrayList();

catArray.add("Naming Convention ");
catArray.add("Basic Profile ");
catArray.add("Non-Stanbdard ");

dataSet.setValues(catArray);
}


} ==============================================================================
If I want to use the different colors to each bar in the graph how can I improve the script.

Thanks

I managed this without script by using "Edit Chart>Format chart> Series >Color By :Categories (I selected 'Categories' instead of 'Value Series').

Please let me know if I my approch is wrong.
