I experience the following, most likely easily solved problem: When I
plot the subrange of one histo and plot another one on top of it, the
second histo doesn't stay within the range of the first one. This only
happens when the second histo is plotted with error bars (either by giving
the "e" option when plotting, or when histo2->Sumw2() was used earlier).
I use root version 2.21/08 on a debian Linux PC.
Demo macro:
{
TH1D* one = new TH1D("one","first one",100,0,1);
one->FillRandom("pol0");
one->SetLineColor(1);
one->GetXaxis()->SetRange(20,30);
one->Sumw2();
TH1D* two = new TH1D("two","second one",100,0,1);
two->FillRandom("pol0");
two->SetLineColor(2);
two->Sumw2();
one->Draw("");
two->Draw("same");
}
