When I use the option “SAME” in the drawing of a 2nd histogram in 1D, I see the 2 histograms superimposed on the same pad, which is ok.
When I do the same for 2 histograms in 2D, using option “LEGO” for the first and “LEGOSAME” for the second, I see only one histogram, the bin content of which is the sum of 2 histograms, which is not what I wanted. Is it a feature or a bug? Is there a way to obtain in 2D the same behaviour as in 1D? Thanks a lot in advance.
