I made the simple macro to superposing several histogram in same canvas.
Each group histogram are in different root input files. I use the TList to access the GetListOfKeys in these root files and I made a loop all the objets of ROOT file directory.
However, in each loop this script see does not same the object in each file.
I would like to access same root object in different root file in same time.
You can see the root macro here.
Could you clarify this point for me?
Thanks in advance,
