I'm creating a chart and i try to define color for this chart using a
ChartEventHandler class. My goal is to associate e.g. color "red" to
"SportCars" or color "blue" to "Oldtimer", so if i generate pdf or html
sportcars have everytime color red in my chart.
How can I do that?

Thank you chakravp,
that's exactly what i am searching for, BUT...
that colors only my legend in red, the color of the part "Oldtimer" in my
chart stays green.

I found the way on my own,
i have to make the same as for legend in method "beforeDrawDataPoint"
function beforeDrawDataPoint(dph, fill, icsc)
{
val = dph.getBaseDisplayValue();
if (val == "SportsCars")
fill.set(255,0,0); // color red
else if(val == "Oldtimer")
fill.set(0,0,255); //color blue
}
