Stack bars selectively and keep the color in barchart

[#1]

Dear all,

I am working on a barchart for a cashflow representation. I have 3 bars, and I would need to stack 2 bars, but I would like to have 2 colors on this new bar.

For example the result should be a red bar and a bar that is part blue and part green.

I am attaching a sample qv file.

See here. Same class of problem. That solution should work for you too.
