Hi, hope you are doing great!
I have three different root files containing leaves. I wanna merge three leaves (from three different root files) into one pad. How can i do that?
I am using Root 6.18.04 along with G4.10.06.p01.
Your response will highly be appreciated.
Thanks

You can make a TChain with your trees in the different
files and Draw() them
