Hi Rene,
Thanks for quick reply. I forced call to " c1->Update ". I didn't
face any problem of illegal pointer. When I clicked on the canvas then
it is showing the second statistics box. I am using the following lines
of my script
--------------------------------
h2->SetFillColor(46);
h4->Draw();
h4->SetTitle("L1 E_{T} Distribution of Crystal No. 4 & 2");
h4->GetXaxis()->SetTitle("L1 E_{T} (in GeV))");
h4->GetYaxis()->SetTitle("No. of Events");
h2->Draw("sames");
c1.Update(); // From your suggestion
TPaveStats *st = (TPaveStats*)h2->GetListOfFunctions()->FindObject("stats");
st->SetX1NDC (0.5);
st->SetX2NDC (0.7);
c1.Update(); // for writing in a new page of the postscript file
----------------------------------------------
Could you please tell me the possible solution for the following
1. What change should I do in the script so that it automatically write
the statistics of the second histogram ? At present, I have to click on
the canvas to get the second histogram.
2. There are several histogram in my script. I am storing all the
histogram in a postscript file. In the above script, I am calling two
times "c1->Update" for the same figure. Hence, it will generate two
pages for the same figure. But, I want one pages for the same figures.
Thanks and with regards,
manoj
