OVR - Chart Coloring

Hi,

I have stacked bar charts (percentage wise) on my interactive OVR, which prints the percentages of the process statuses at a point of time. So processes in Error are flagged Red, those in progress are in Yellow, Completed are in Green, and those requiring 3rd party inputs are Blue.

Now I need to color code the chart appropriately. I have set the series color code for the chart accordingly (R, Y, G, .

What happens, if the data has all the 4 colors, the series color codes come correct. Now if I have only the Red, and Blue colors, the Red category is assigned to the Series 1 and Blue to series 2. So the Blue shows up as yellow color in chart.
