Using your age example I am trying to color the data for the 0-15, 16-21 and 30 and up ages black, but color the 22-30 year age data red. So, the x-axis data is of the same scale, I'm just trying to figure out how to separate it visually. I guess the @xdata1 would be something like ["0-15", "16-21", "30+"] and @xdata2 is ["22-30"]. I can combine them into one array and pass it into GD::Graph just fine, but I can't get the color delineation.
