Histogram filling problem

Dear Rooters,

I want to study the number of fired PMs in a detector. When I plot the histogram with using predefined GetNbPMV0C() function, I see that last point of the histogram is on 33, but it should be 32 because of the detector has only 32 pms. So, do you have any idea about this situation is normal or not.

Thank you,

Kind regards,

Ayben

[quote]So, do you have any idea about this situation is normal or not. [/quote]Probably not … but I can not really tell from your short description (the problem could be misreading the graph, could be numerical errors, could be semantic of GetNbPMV0C, etc.)

[quote] When I plot the histogram with using predefined GetNbPMV0C() function[/quote] GetNbPMV0C is not a predefined function of the ROOT framework, I am guessing it is provided to you by your collaboration (framework) and you might want to ask help from within your collaboration.
