Note that the histogram and pdf are on inherently different scales; for example, if your sample had 10 times as many observations, then the histogram's Y axis would expand by a factor of 10, but of course the pdf values don't change at all. Although fitting a curve to a histogram is usually not optimal, there are sensible ways to apply special cases of curve fitting in certain distribution fitting contexts.
