Conditional Chart Formatting

Hey all, I'm trying to make a bar graph I have, conditionally change colors depending on the value of a certain field.

example chart: http://img.photobucket.com/albums/v1...k/image001.png

what I'm trying to do, is color the AMD chips green, and the Intels blue to better help differentiate the information, I can do that via fill options, but every time I change a field, the color no longer applies to the right value.

Is there an available plug-in? or is this buried deep in excel somewhere?

Thanks for any help in advance,

So basically creating multiple series from one, I might be able to do that. so there isn't actually a function for chart conditions in itself then....hmm, MS may want to consider that for O13

Thanks, I'll play with that tonight, see what I can't do, my database has become multiple pages long, lol
