Dynamic series color for bar chart

[msafi]

Hi

  How to set dynamic colors for a bar chart, my plot looks likes this, the hardcoding of the color works, but i wanted to pass a set of colors as parameters and use them in plot series, is that something possible? Please Suggest.

 

<bar3DPlot isShowLabels="true">
                    <plot>
                        <!--<seriesColor seriesOrder="0" color="#3A6E90"/>-->
                         <seriesColor seriesOrder="0" color="$P{primary_color}"/>
                        <seriesColor seriesOrder="1" color="#F58029"/>
                        <seriesColor seriesOrder="2" color="#53BDEC"/>
                        <seriesColor seriesOrder="3" color="#6A8098"/>
                        <seriesColor seriesOrder="4" color="#7F8084"/>
                    </plot>

reading more on forum looks like there is no straight way of doing this, can some one help me here on, what customization needs to be done if i need to change my seriesColor at runtime (i.e) what base classes that i need to modify?
