I have a root file with a tree. I need to write a macro to access the histogram from the tree. Opening the root file in the terminal and using the command tree.Draw(“leafname”) gives me the histogram. But I need to write a macro and access the histogram. Thanks!

tree, root, hist

Hello! I’m filling a tree and after I, sometimes, get this funny behavior AUX;1 AUX;2 with the same histograms inside but with different events in each ;1 and ;2… Can somebody please tell me why this is happening? Many thanks, Stefanos
