Hi,
I want to use a function to control the weighting of histograms projected
from an ntuple. i.e. I define some function
float weight(float var) { .... return weight;}
and then when I project the histogram I use this function and a variable
from the ntuple:
nt->Draw("x>>h1","weight(z)")
where x and z are ntuple variables. The problem is that I get an error
message
Unknown name : "weight(z)"
Now this does work if I use some library routine like sin(z). How can I
define my own weighting functions? Thanks,
Scott Sampson
