I have two trees in two different root files.
I want to get tree1, draw a histo.
Then I want to get tree2, draw a histo of the same variable
with nbins, xmin, xmax ( x axis range) same as the tree1 histo.
This is what I am doing :
h1 = (TH1F*)gDirectory->Get(“h1”);
double xmin = h1->GetXaxis()->GetXmin();
double xmax = h1->GetXaxis()->GetXmax();
double xbins = h1->GetNbinsX();
h2 = (TH1F*)gDirectory->Get(“h2”);
h2->SetBins( xbins,xmin,xmax );[/code]
h2->SetBins( xbins,xmin,xmax ), if I do
it shows me the same maximum as it was before
Do I need to something else to ensure that the binscontents are evaluated again after
the nbins, xmin and xmax of h2 is changed?
I would like to mention that both h1 and h2 have different nbins, xmin and xmax
Thanks & Best Regards,
