Hello,
The draw-option "L" doesn't seem to work if Sumw2() on the histogram is
set. This is what happens:
[root] TH1F* h = afile->Get("a_histo");
[root] h->Draw("L")
(looks right, line is drawn)
[root] h->Sumw2()
[root] h->Draw("L")
(line is *not* drawn)
Am I doing something wrong, or is there maybe a way around this?
I would like to draw the histogram with the options "E3" and "L", and I
create it with TH1F::Divide, so I really need to set Sumw2. I guess I
could copy the final histogram to a new histogram by setting the bin
content and errors manually bin by bin, then draw the new histogram.
I'm using root 3.03/09 on Linux RH6.
Regards,
Paul Balm
