Hi all, I can't seem to be able to make a thermal plot of a 2d histogram. Here is a simple example: ghist = new TH2F("Gaussian","This is a gaussian",10,-10,10,10,-10,10); gRandom->SetSeed(); for (Int_t i = 0; i < 1000; i++) {ghist->Fill(gRandom->Gaus(0,5),gRandom->Gaus(0,5),1);} gStyle->SetPalette(1); ghist->SetContour(28); ghist->Draw("colz"); I get a palette with 2 colors and a blank plot! Is this a bug or am I doing something wrong? thanks, Greg Veramendi CDF online monitor framework
