I would like to make a projection from a sparse type object to 1-dimensional histogram in variable bin sizes but I got wrong number of entries at the end of projection which I don’t understand where I’m doing wrong.
I defined 3 different histogram with following intervals to check the code ,
hist1- from 0 to first bin,
hist2- first bin to second bin in the loop,
hist3- second bin to last bin.
I’m expecting that hist2-(hist3-hist1) should be 0, but I got different numbers for each projection bin.
Root file and the relevant macro is attached. Please help me to solve this problem.
