I have a histogram (see below) and I am trying to find the mean and standard deviation along with code which fits a curve to my histogram. I think there is something in SciP
Kind of an old question, but for anybody looking just to plot a density fit for a series, you could try matplotlib's .plot(kind='kde'). Docs here.
.plot(kind='kde')
Example with pandas:
mydf.x.plot(kind='kde')
