I am fresh new to root.
And when I cloned histograms, I forgot to give it a specific name other than the original one. So I am stuck when trying to use the histograms again.
Here is what I have when do a .ls()
OBJ: TH1F h1 h1 : 0 at: 0xa4e24a0
OBJ: TH1F h2 h2 : 0 at: 0xa502ba8
KEY: TH1F h1;2 h1
KEY: TH1F h1;1 h1
KEY: TH1F h2;3 h2
KEY: TH1F h2;2 h2
KEY: TH1F h2;1 h2
Is there a way to rename these histograms?
