I would suggest that you avoid the histogram and make a density plot
instead. It would be more informative and probably require a lot less

compare the histograms. If they're not much different in shape, it's
likely that the full sample is close to the same. If there are
noticeable differences, try 50000 or 100000 instead (rinse and
