Hi all,
While I am learning how to 'bin' properly, I have discovered something
odd, maybe somebody could explain that/
I attached a mini script which creates two histograms, filled by a
simple vector with values from 1 to 10, only that the second histogram
has a wider range to cover with the same number of bins, therefore the
bin size should be smaller than in the first histogram.
Why does it then look from the plot as if the bins are bigger in the
second histogram?
Many thanks,
Michael Aye
