Dear Root users,
I have a 2D histograms “hxy” with X & Y axis as variable A & variable B. I want to project axis B for specific values of A (like 200 < A > 400). To achieve this presently I am doing :
TH1D *h1= hxy->ProjectionB("",200,400);
With this I am not getting the correct statistics in histogram h1. Is this the correct way ?
If not then please tell me the correct method.
