Way to scale up two histograms into a TProfile

[hep_physics]

Is there a way to scale up branches in a tree simultaneously and plot into a profile ?
something like

tree->Draw(“hprof”, '“x:y”, “10”, “20”)
10 for scaling up x, and 20 for y ?

How about this (TTree::Draw)?

tree->Draw("10*x:20*y","","prof")

Doesn’t work unfortunately, stretches the x and y axis

Then your issue is not clear to me. Could you explain what you mean by scaling?

[hep_physics]

I have two branches x, y. I want to scale x by 10, y by 20 and do a TProfile on them. By scaling I was referring to raising/lowering the bin contents.

[ksmith]

You want to have the contents weighted then? You description of weighting is not quite clear, it seems to me you want every been scaled by 200? Maybe a small example is needed.

Because with the methods I know I can only weight one branch or one histogram, but when there are two I was wondering how to do it.

I guess that makes sense, yes, weighting is the word I was looking for.
