Hi,

supposed I have a splitted Tree with the float values X,Y,Z.
Is it then possible to put these values into a 2 dimensional histogram
with weight Z summing up in the bin at X,Y ?
I can do this in a loop reading events from the tree and filling a
histogram, but I would prefer it done in a command like
Draw("Z:Y:X>>h2") . Is here a solution?

Dirk
