Add different color to one bar series from script based on dataset value.

Hi all,
Below I had displayed the code that will change the color of bar chart .But i have 2 y-series and this code will change color of both series.Does anyone have idea how to change color of only 1 series?Thanks in advance.

function beforeDrawDataPoint(dph, fill, icsc)
{
importPackage( Packages.org.eclipse.birt.chart.model.attribute.impl );
val = dph.getOrthogonalValue();
if( fill.getClass().isAssignableFrom(ColorDefinitionImpl)){
if (val == "string" ){
var mycolor = ColorDefinitionImpl.YELLOW();
r = mycolor.getRed();
g = mycolor.getGreen();
b = mycolor.getBlue();
fill.set(r,g,b );
}
}
}

You can change the colors in the charts beforeDrawDataPoint function.
Attached is an example that sets each column to a different color based on either its column label or column value. I've also included series color code for reference.
Below is the code used in the charts onRender method:
 
 
//Sets bar color function beforeDrawDataPoint(dph, fill, icsc) { 
 name = dph.getBaseDisplayValue(); //Get label 
 val = dph.getOrthogonalValue(); //Get value 
 
 if (name.indexOf("Australia")>=0) //If label contains Australia 
 fill.set(255, 0, 0); //Make red 
 else if (name.indexOf("France")>=0) //If label contains France 
 fill.set(0, 255, 0); //Make green 
 else if (val >= 80000 && val <= 90000) //If value is between 80000 and 90000 
 fill.set(0, 0, 255); //Make blue 
 else //else 
 fill.set(122,186,242); //Make default blue 
} //end 
 
 //Sets Series Legned color function beforeDrawLegendItem( lerh, bounds, icsc ) { 
 var label = lerh.getLabel().getCaption().getValue(); //Get label 
 if( label == "Series 1") //If label matches Series 1 
 lerh.getFill().set(200, 200, 200); //Make gray 
 else //else 
 lerh.getFill().set(122,186,242); //Make default blue 
} //end
