I have a file with many similar TH1D histos, one for each runnumber: each of it plots the number of entries (y-axis) for each chiSig (x-axis).
Is there a simple way to take all of these histos and put them into a 2D-histos plotting chiSig versus the runnumber?
Or do I have to fill every bin of the 2D histo individually?
I appreciate your help!!
