Thanks but that makes the entire stacked column a single color.
Maybe its best to explain my data set.
I have a field called "Lap Count" with the values "Lap 1","Lap 2"," Lap 3", ...
My stacked graph is stacking the field "Lap Time".
I think I need to go into the the data tab for "Lap Time" and use a set expression that tells it to make Lap Time RED when Lap Count = Lap 1 on so on.
I think that is the correct way but I am new and even if this is correct, the syntax is eluding me.
