Dear All,
I am facing a problem in the use of TProfile I have plotted radiation length map by using TH2D and TProfile in TH2D X/X_0 vs theta is going up to 1.5% of X_0 but in TProfile It is going up to 0.7% of X_0 however macro used is same. Is there some problem with TProfile? Plots are attached.

Thank You
Shyam

Thanks for reply, I have plotted the radiation length map by using the same code in one case I have used TH2D for filling and drawing the ( x/x0 vs theta and x/x0 vs phi) in other case I have used TProfile for filling and drawing ( x/x0 vs theta and x/x0 vs phi). I have used the same code in both case but plots are looking very different why?

Taking a TH2 histogram and doing->ProfileX(...), not filling a TProfile. I have no idea what that code is doing.

Hi,
The Problem is solved, Since TH2D and TProfile are the two different approaches, In TH2D entries are filled like (x,y) but Tprofile It shows the values mean value of Y for each bin interms of entries so we can not compare them. I have written a test macro (attached) to check it.

Thank You
Shyam
