Contribute examples to pandas

[jankatins]

Pandas is currently deprecating their rplots (trelis plots, what we call faceting) module and it would be nice if ggplot examples are contributed to their examples to replace them.

I don't think we are currently ready for primetime yet, as we don't handle categorical data in faceting very well. So contribute there after fixing that problem at our side...

See here:

Some difficulties/missing things that I encountered when I tried to convert the examples:

• I first tried to use facet_wrap giving it a list (which gave a not so informative error message), but then used (correctly I suppose) facet_grid. Thing is: both have no docstring, and the example pages on the website are broken (no images visible): http://ggplot.yhathq.com/docs/facet_grid.html and http://ggplot.yhathq.com/docs/facet_wrap.html

• When doing this:

  ggplot(tips_data, aes(x='total_bill', y='tip')) +\
  geom_histogram() +\
  facet_grid("smoker", "sex")
  

  The y-label showed 'tip', which is not correct I think as I plotted a histogram, not a 2D plot (OK, I provided the y variable myself, but is is not fully correct)

• Missing functionality (as far as I can see): something to do the rplot.GeomPolyFit(degree=2) and rplot.GeomDensity2D()

So actually, the basic examples already can already be done, it is more some details/more advanced functionality that are missing.
