Changing color of Bar chart

Is it possible to change the color of the bar chart based on data?

Would changing the Palette selection based on Value series instead of Category work for you? This is under the Chart Editor/Format/Series section.

I have accomplished my requirements by firing a script during the rendering of the chart.

//To show correct colors for all sections of the Bar chart. The color will be based on the Category.
function beforeDrawDataPoint( dph, fill, icsc )
{
var sValue = dph.getDisplayValue();

if (sValue.contains("1CPTP"))
{
fill.set(148, 198, 222);
}
}

Hi Is it possible to set the dataset value of RGB color dynamically? instead of doing

if (sValue.contains("1CPTP"))
{
fill.set(148, 198, 222);
}

I want something like below,

colorVal = (148, 198, 222);
if (sValue.contains("1CPTP"))
{
fill.set(colorVal);//dynamically
}

jain I haven't tried it but I think you should be able to do what you're trying using persistent global variables in you're report. You could create three say r, g, and b. And set the values somewhere else in a function you create and call them in your beforeDrawDataPoint() making it dynamic.
