Hi, in some cases I think ROOT tries to be a little too smart when drawing histogramms. Maybe one can reconcider some functionality. 1) Why doeas the following draw Polymarkers even if I don't specify "P" ? How can I switch the markers off? Only by setting the size to 0? TH1F *f = new TH1F("h","h",100,-3,3); f->FillRandom("gaus"); f->SetMarkerStyle( 22 ); f->Draw("E"); 2) Why does the following draw errorbars even if I don't specify "E"? How can I switch it off? TH1F *f = new TH1F("h","h",100,-3,3); f->FillRandom("gaus"); f->Sumw2(); f->Draw("P"); I think it would be more intuitiv, if ROOT draws error bars when I specify E and doesn't if I don't, same for polymarkers, but this only my personal opinion of course.
