Thank you Ralf,

I already knew this way, unfortunately I need to plot a combination of different variables, but for each of them I need to apply different cuts, so this way is not usable for this particular case.
I mean, it would be something like:

data->Draw("atan(Py/Pz) - atan(Py/Pz)", "cuts"...) for which the first Py and Pz needs a cut on PdgCode==11 and the second pair a cut on PdgCode==22...

If this is possible, could you give an explicit example?, please.

Thanks again for your help Smile
