Hi!

I was drawing TH2 histograms and I would like to draw a filled contour plot on top of a lego histogram. For example, I want to put the contour plot of the right image on the top of the left one.
Someone knows how can I do that?

Thanks in advance!

{
   hpxpy->Draw("lego2");
   TH2D *h = (TH2D*)hpxpy->DrawClone("surf3 same");
   h->SetLineColorAlpha(kRed,0.);
   gPad->Modified();
   gPad->Update();
}
