Dear Rooters,
I had a problem when I wanted to draw a bar chart in ROOT 5.18:
I looked into the THistPainter, to remind myself of the various options. There I found in the section “Options supported for 1D histograms”
This option, however, does not have any effect in ROOT 5.18 even though the documentation says so.
{
TH1F f("f","F",100,0,100);
f.FillRandom("pol1");
f.SetFillColor(kBlue);
f.Draw("B");
}Only by chance I looked further down and discovered the description about the “BAR” and “HBAR” option.
Now I discovered that the problem does not seem to be there in ROOT 5.22.
Was there a problem in 5.18 which inhibited the usage of “B” or is the documentation not correct for that version?
Cheers,
Erik
