How can I check the number of entries in a Graphic Cut in a 2D histogram.
_ROOT Version:6.04
_Platform:Ubuntu 18.04 LTS
Compiler: Not Provided
In general, you can get the number of entries by calling <histogram>->GetEntries(), e.g. h2->GetEntries(), either in the ROOT prompt or in your macro. But perhaps you mean something else? Do you have a code snippet for illustration?
Actually I am asking for getting number of counts in a Graphic cut that I can apply through the editor option of TBrowser. I had a Neutron time of flight vs PSD plot and I want to know the number of counts in neutron lobe.
May be this can help:
