Superimposing two ntuples from different root files

Hello everyone, can someone give me a script allowing me to overlay two ntuples from two root files?

What do you mean by “overlay”?


I would like to put on a same graph two plots (ntuples: x & y) which from to two root files (x.root & y.root), in order to make a comparison.

Many thanks.

Do the second plot using option SAME.
