Now I have several TH1, with the x-axis have the same binning, can I convert them to a TH2, which has the same x-axis as TH1, and the each bin of y-axis stands for a TH1. The bin content of the TH2 is the bin content of the TH1.
I know, I can accomplish it with the loop and set bin content. Is there any easier way to do so?
I hope it’s clear.
Thanks in advance.
