how to program bar plot color with the property node

[DavidWei]

I want to make the bar plot color can follow the group number. I use the property node to program the plot color. but it's very strange. from the attached example, we can see the color of the line plot can be programmed. while the color of the bar plot doesn't. I believe there must be something wrong. but I cannot figure it out. Anybody here can help me to debug this problem? thanks in advance!

You need to change the fill color instead:

Oh, and btw, your inner while loop is pure Rube Goldberg. See if you can simplify it!

One possibility....

(The error should be wired to avoid auto error handling, but there are other ways, of course.)
