Re: TH2 Projection in respect to generic axis

This functionality (although not very precise) could be implemented in the ProjectionXX functions.
However the solution is to start from a Tree and instead of

    T.Draw("y:x")
do

    T.Draw("transform(x):transform(y)")
where transform are functions linear or not of the variables x and y.
