Make a Tree cut using user-defined function

General Chat

Hello,

To clarify what I need, I’ll illustrate through the following example:

I have a tree that has two Branches: x and y.
I would like to select the events where y is less than func(x)
I prefer to do it in .C macro program, is it possible to have the command below or similar ?

tree->Draw(“y:x”,“y<func(x)”);

Regards,
hicho

Hi,

Yes. You need to make sure to load into CINT either the definition (if you want it to be interpreted) or the library and dictionary for your function.
