Hi, In the mailing list I found the info, that TH2D::DrawCopy(Option_t ...) should work with different options since v3.00. (see: [ROOT] TH2D::DrawCopy() C.Plettner (Thu Feb 22 2001 - 13:16:17 MET) Re: [ROOT] TH2D::DrawCopy() Rene Brun ... ) But I can't reproduce this ... When I try the following example with TH2F, it works as expected, but with TH2D the "DrawCopy"-image is only a scatter plot... { gROOT->Reset(); //TH2F h2("h2","xygaus + xygaus(5) + xylandau(10)",20,-4,4,20,-4,4); TH2D h2("h2","xygaus + xygaus(5) + xylandau(10)",20,-4,4,20,-4,4); gStyle->SetOptStat(0); gStyle->SetPalette(1); gStyle->SetCanvasColor(33); gStyle->SetFrameFillColor(18); TF2 *f2 = new TF2("f2","xygaus + xygaus(5) + xylandau(10)",-4,4,-4,4); Double_t params[] = {130,-1.4,1.8,1.5,1, 150,2,0.5,-2,0.5, 3600,-2,0.7,-3,0.3}; f2.SetParameters(params); h2.SetFillColor(46); h2.FillRandom("f2",40000); TPaveLabel pl; Float_t x1=0.67, y1=0.875, x2=0.85, y2=0.95; Int_t cancolor = 17; // Draw() TCanvas surf("Draw()","Draw()",200,200,800,600); h2.Draw("surf1"); // DrawCopy() TCanvas test("DrawCopy()","DrawCopy()",200,200,800,600); h2.DrawCopy("surf1"); } Did I miss something?
