Hello,
I am trying to produce random numbers according to the data of a spectrum with bins of variable size. I use: h->GetRandom() to generate energies following this spectrum. Then I fill an output histogram with the randomly generated numbers.
The problem is that, depending on how I define the bins of the histogram that I fill, the result looks different (see attached picture):
- If the histogram is defined with the same bins as the original one, the result looks good (red line).
- If I define the histogram with a constant bin size, I see the steps of the original bins (blue line).
I would like that the data is smoothly distributed, following the original smooth line, and without depending on how the output histogram is defined. Is it possible to do that?
I send also attached a data file and a function to reproduce the problem, if needed.
