How to acces TH1D in a root file

i have a canvas stored in a root file. On this canvas there is a single frame in which 3 histograms are plotted (with “same”). Unfortunaltely all 3 histogram have the same name “outs”.
When i open the root file in a TBrowser and then type


i get the bin content of only one of the three histograms.
Is there any way to access the other two also?
Maybe I should have given them different names from the beginning… Is it possible to change the names afterwards, when it is already stored in the file?

Thanks for your help

…sorry for posting too fast :wink:
of course it is possible to change the name via SetName and then one can work with them as usual
