Graph histogram and normal density with pandas

Question

I look for graphing both normal density and histogram density from a serie df like that but don't achieve. like link below http://hypertextbook.com/facts/2007/resistors/histogram.gif

How to do that with DataFrame objects ?

>>> fd
Scenario
s0000      -2.378963
...
s0999       1.368384
Name: values, Length: 1000, dtype: float64
>>> fd.hist(bins=100)

I think you can first plot the histogram like fd.hist()

Then fit the normal density and plot it with matplotlob, please refer to:

Surely but there is no automatic way ? I think it's a common need – Alexis G Aug 14 '15 at 14:37

fig = plt.figure()
ax = fig.add_subplot(111)
fd.hist(ax=ax, bins=100)
ax1 = ax.twinx()
fd.plot(kind="kde", ax=ax1, legend=False )

Adapted from https://stackoverflow.com/a/26913361/841830 which shows the more complex case of two histograms and two density plots.
