On my system, the option "col" doesn't function at all.
(linux, libc5, root 2.0.13)
Here is a interactive root-session as a example:
root [0] TH2F myHH("Tt1", "TT2", 8, 0., 32., 32, 0., 16.);
root [1] myHH->SetBinContent(34,10.);
// the following options are functioning correctly!
root [2] myHH->Draw("lego");
root [2] myHH->Draw("lego1");
root [2] myHH->Draw("lego2");
root [2] myHH->Draw("lego3");
root [2] myHH->Draw("surf");
root [2] myHH->Draw("surf1");
root [2] myHH->Draw("surf2");
root [2] myHH->Draw("surf3");
root [2] myHH->Draw("surf4");
// with the following options only a empty hisogram is drawn!
root [3] myHH->Draw("col");
root [3] myHH->Draw("cont");
root [3] myHH->Draw("cont1");
What am I doing wrong?
Many thanks in advance!
