Hello! I've got data in a TProfile. Now, I want to count the number of events between two values on the X-Axis scale. I tried TH1::Integral. But the problem is, that I have to give the limits of the integral in bins an not in X-Axis values. Is there a method that converts X-Axis values in Bins? I've found TH1:GetBinWidth. This method gives the stepsize between the bins. How do I find out the shift between the X-Axis scale and the bins? To have the stepsize AND the shift would solve my problem. Thanks Christian -- ___________________________________________________________________ Christian Haeberli christian.haeberli@cern.ch University of Bern Laboratory for High Energy Physics Phone : ++ 41 31 631 4069 Sidlerstr. 5 Mobile: ++ 41 76 316 6159 CH-3012 BERN Fax : ++ 41 31 631 4487
