Hi Manoj,
The piece of code you are talking about is the following I guess:
TGraph *gr = new TGraph (nBINeta, x,y);
TH1F *h1 = new TH1F("h1","h1",nBINeta,1.5,1.9);
h1->SetMaximum(1);
h1->SetMinimum(0);
gr->SetHistogram(h1);
TAxis *axis = gr->GetXaxis();
axis->SetLimits(1.5,1.9);
gr->Draw("AC*");
I think you can remove the lines:
TAxis *axis = gr->GetXaxis();
axis->SetLimits(1.5,1.9);
as you set yourself the histogram. But this doesn't explain why you get
that crash. Are you sure that nBINeta is always valid ? To book the
histogram you can use a fixed value (100 for instance). Sorry to not help
more but I cannot execute your macro which requires many files I do not
have.
Cheers, OlivIer
