ENH/VIS: KDE plot can be cumulative

[sinhrks]

I sometimes want cumulative density plot for distribution comparison. Added cumulative to KDE plot, like matplotlib.pyplot.hist.

import pandas as pd
import numpy as np

s = pd.Series(np.random.randn(100))
s.plot(kind='kde', cumulative=True)

@TomAugspurger didn't we have a discussion about not adding this once before? (as its in statsmodels)

[TomAugspurger]

Yep. It's implemented in seaborn now. See the very end of this section. It basically wraps statsmodels' / scipy's kde function.

This was the issue: #2669

Basically decided it was out of scope for pandas, especially since there are so many great plotting alternatives being built.

closing as out-of-scope

Ah, OK. I thought it is kind of stacked=True operation though.
