Hi,
I'm dealing with data that has been sent to me as a ROOT tree in 2 channels,
so I can plot histograms using the cuts
mytree->Draw("mean","readoutType==1")
or
mytree->Draw("mean","readoutType==2").
My problem is that I want to plot the mean of readoutType 1 against that of
readoutType 2.
That means that I need a different cut on the y-axis to that on the x-axis.
I've asked around, but no-one seems to know how to do it. Is it possible?
Many thanks,
Phil
