Hello everyone,
Does anyone know how I can make a histogram of some root files that have different cross sections and luminosoties ? how should I normalize them ?! is it possible I normalize them before running my code over them?

Thank you, I had seen this before but was not sure exactly which is the right method for my code. I have found my answer now.
