How do I set transparency in Histogram (Area fill opacity like in Bell Curve)?

It looks like in RapidMiner 9.2+ it is not possible anymore to plot two overlying histograms (e.g.: one for the positive class and another for the negative class) and actually see both of them at the same time.

Interestingly enough, the transparency is available in some other graphs, like in "Bell Curve".

    • For printing: You can left-click on the individual colors of the Color palette, and set the transparency for each color to e.g. 40%. The result will be something like this:
