Re: [ROOT] Multiple cuts on different axes

Thanks Rene and Philippe.
My histograms look different if I do 
myTree->Draw("mean*(readoutType==1)","correlatedHit==1")
or if I do
myTree->Draw("mean","readoutType==1&&correlatedHit==1")

The necessity of the correlatedHit cut is probably self-explanatory. Is the 
second cut being applied in this case? The distributions look different (the 
former has many more hits at/near 0).
How about in the case below, since I have no way of checking this?

myTree->Draw("mean*(readoutType==1):mean*(readoutType==2)","correlatedHit==1")

Cheers,
Phil
