Hi Rene

Well I have the original info in a tree where i applied slightly different cuts.

Because I did not find any thing where I can plot the two variables as a 2D histo with slightly different cuts.

Is there any thing or you are suggesting that I should create a tree from these h1 and h2 which i created from a tree with 2 slightly different set of cuts.
