Hi Muhammad,

try drawing your histogram using

hist->Draw("C");

It will draw a smooth curve through the histogram bins.

Hi @yus I tried but it draw small circles at the top but not a smooth curve .

A histogram is a representation of counts; the line you see corresponds to the counts of how often each bin was filled. Changing the line means changing the histogram contents - which means showing not the data you have but data you believe to be better. The deviations from the “perfect line” are important, though - they give an indication what the uncertainty is.

I see two options:

  • show a fit, i.e. a function that parameterizes your histogram.
  • use larger bin widths; you can try for instance hist->Rebin(4)

Cheers, Axel.
