Draw several TH2F using PSR

ROOT
1

Hi!
I am trying to draw three TH2F in PSR (pseudorapidity coordinates) into one canvas. My problem:
h1->Draw(“PSR”) doesn’t work.
If I’m using the GUI to change it, i select one Histogram and select 3D and PSR. That works fine.
But after that, i can see but can’t select another histogram. It seems to be covered by the 3D-histogram.
Any ideas?

[code] ctemp.cd();
EventDisplayCL->Draw(“psr”);

			ctemp.SaveAs("./EventDisplay/"+eventdis+"CL.eps");
			ctemp.SaveAs("./EventDisplay/"+eventdis+"CL.root");

			EventDisplayMC->Draw("psr,same");
			ctemp.SaveAs("./EventDisplay/"+eventdis+"MC.eps");
			ctemp.SaveAs("./EventDisplay/"+eventdis+"MC.root");

			EventDisplayTRK->Draw("psr,same");
			ctemp.SaveAs("./EventDisplay/"+eventdis+"TRK.eps");
			ctemp.SaveAs("./EventDisplay/"+eventdis+"TRK.root");[/code]

The PSR option should be used together with one of the LEGO or SURF options as explained here:

The option SAME has some limitations explained here:

I would recommend you use an histogram stack:
