I’ve got a bunch of histograms in a file - a file I would prefer not to recreate. The histograms had Sumw2() run on them. I would like to plot them with some fill color ( I don’t mind losing the error bars ). After running Sumw2(), SetFillColor() has no effect.
TH1F* hist = new TH1F("hist", "myhist", 10, -1, 1); hist->FillRandom("gaus",10000); hist->Sumw2(); hist->SetFillColor(4); hist->Draw();
How can I SetFillColor() of a hist after Sumw2() has been run on it?
