More than one graph in a Canvas

[couet]

Philippe,

I think you can ignore this post. I have already answered this question (and many more !) here:

Opening two .root file in the same canvas

Hi Every Body, I have two .root files including histograms. I got them from AIDA in geant4. For opening these files I need root. I need to open these two files in one canvas in order to be able to compare them. I am wondering should I write a c++ code for that or can I do it easily from the browser? Really thank for your help
