Convert canvas into histogram in root

[mendoza]

Dear experts,

I am sorry to bother you. I am trying to implement your code in my program, but using pyroot. I can make it work and I don’t know what more to do.

Thanks for your time and I apologize again.

Convert canvas into histogram in pyroot

Dear Users, I use PYROOT and I have a TFile with a canvas inside. I need to convert it into an histogram because I will work with it after. I have used some of the topics very related to that but it does not work, maybe because I am using PYROOT.
