Drawing TH2 contours, incorrect (?) regions being shaded

[Birdsall]

I have been doing some searching, and I found this

Contour Plot / access contours

Here you go: File cont.c void cont() { h_cont = new TH2D("h_cont","test", 10, 0, 10, 10, 0, 10); for (int i=0; i<10; i++){ for (int j=0; j<10; j++){ h_cont->SetBinContent(i,j,i*j); } } TCanvas *c1 = new TCanvas("c1","ctest"); c1->Divide(1,2); c1->cd(1); h_cont->Draw("CONTLIST"); c1->cd(2); TObjArray *contours = (TObjArray*)gROOT->GetListOfSpecials()->FindObject("contours"); TList *list = (TList*)contours->At(0); TGraph *gr1 = (TGraph*)list->F…

It seems that it might be possible to get the x,y coordinates of contours, but that this does not work for “CONT3SAME”, only “CONT” drawing options.

I will ask another question about it as this has become a different issue and this appears to be a bug.
