Hi rooters,
If I have N trees in the chain and like to have the access to tree ID from the chain.Draw() is it possible?
For example: from the TTree:Draw function I can access tree entry as: tree.Draw(“Entry$”)
in case of chain it plots the entry number for each tree as well.
In case of chain it could be nice to have 2 more options - smth like:
chain.Draw(“ChainEntry$”) - for the cumulative entry number in the chain
and
chain.Draw(“TreeEntry$”) - to access the tree ID (from 1 to N in my example).
Regards,
Valeri Tioukov
