change the color pattern of bar chart in webdynpro

Hi,

I am using business graphics to create bar charts in my webdynpro application. I am using chartType as columns.But i am getting a default set of color pattern for the bars. I want to customize that. I mean i have 3 bars in the output for each category and want to have Red/Yellow/Green color sequence always for those categories. Can i achieve this?

Please share if u have any input on the query.

Thanks,

Pavan.
