Dear co-rooters,
I am facing a rather bizarre issue :
I have a canvas which I divide in 2 pads using
TCanvas *canvas = new TCanvas("canvas", "HPGe", 500, 500);
canvas->Divide(1, 2);
In the bottom pad I draw two histograms, the second of which is defined through
TH1D *histo_rms = new TH1D("histo_rms", "Derivative RMS", 1, 0, histo_1st_derivative->GetBinCenter(points));
histo_rms->SetBinContent(1, -rms_fraction*rms);
The problem is that when I zoom in the x-axis of the bottom pad through the mouse, the histo_rms
histogram disappears, but when I unzoom it comes back again!
Any idea on what might be wrong and how to fix it?
