Hi rooters,
I would like to ask a very basic question:
I have a ntuple defined as the following:
Vertexp(3,nMass)
where 3 stands for the positions (x,y,z) and nMass is the total number of
combinations defined in another ntuple.
Now what should I do to see for example the x postion.
I tried stuff like
ntuple->Draw("Vertexp[0][0]"); and
ntuple->Draw("Vertexp[0]"); without succes because obvioulsy wrong.
Tried to find the solution everywhere on the web site but without much
succes.
Anyone knows ?
Cheers
ps: To use it in root I converted it from a COL_Wise using n2root
