To draw a rotated Pad


I’ve got a Canvas divided (2,2), i.e. into 4 Pads, with a TH2D histogram in (3) and two TH1D histograms in (1) and (4), where my TH1Ds are the x- and y-projections of the TH2D. How can I draw my TH1D y-projection in (4) rotated with the x-axis parallel to the TH2D y-axis?
More in general… how to draw a rotated Pad or a rotated plot into a Pad?
Perhaps a trivial question, but I didn’t find any answers in the User Guide/Reference Guide.

Thanks a lot!

The only way is with the HBAR option
