Add violin plots

[juliohm]

Matplotlib misses violin plots. There is some work on the web, but I don't know if the author pushed it further.

These kinds of plots are quite popular in R and it would be great to have them in Python too.

iirc matplotlib has a no-scipy import policy so that version of the work can not be used directly.

I totally agree with the policy and would rewrite KDE myself if I had time. Too busy at the moment.

If I recall correctly, I think Pandas included support for these plots.

[juliohm]

@WeatherGod, I don't think so. At least I wasn't able to find it in the API reference.

Anyways, the De facto standard for plotting in Python is matplotlib, not Pandas.

You are right, it wasn't Pandas. It was statsmodels:
http://statsmodels.sourceforge.net/devel/generated/statsmodels.graphics.boxplots.violinplot.html

Yes, the de facto standard for plotting in python is matplotlib. However,
that being said, there have been give-n-takes among various packages on who
is responsible for some of the more advanced plotting interfaces. Nearly
all of the other tools (i.e., Pandas, statsmodels, etc.) use matplotlib for
their plotting, just bringing to bear their more advanced libraries to
compute more complicated statistics and data representations.

In the past, the focus has been to push these types of plots over to these
various tools. Lately, however, I have seen some push back -- not
necessarially back to matplotlib -- out of those toolkits and into
something else entirely. Who knows, maybe one day it will make sense to
have matplotlib do all of these plots. But right now, it doesn't fit within
our limited scope of providing cross-platform plotting primitives.

@WeatherGod, thank you for pointing it out. I'm already using bean plots from statsmodels.

Could you please confirm this issue can now be closed?

[tacaswell]

Yup, this should have been closed, thanks for catching that!
