Re: [matplotlib-devel] is R wrong? (boxplot)

[Matt Sundquist]

Hey all,

I thought I'd throw out that a tool I'm working on, Plotly ,
also does box plots with the option to show jittered points. Instead of
passing in stats you pass in an array of values.

Here is a notebook with the box plots with jitter:
nbviewer.ipython.org/gist/fperez/8930306.

You can also view the mean of the array (the dashed line), +/- 1.5 standard
deviations around the median, and the outliers of the set (the hollow
points): https://plot.ly/~ChrisPP/49.

More generally, we're hoping to soon let folks convert matplotlib scripts
into a Plotly graph (GitHub
Issue).
We'd love your advice and thoughts.

Thanks a bunch,
M

Re: [matplotlib-devel] Add labels to points to aid data exploration

[Matt Sundquist]

Hey Raphael,

Jake Vanderplas has been working on mpld3 , which
lets you create D3 renderings of matplotlib graphs. We (Plotly)
are working with him on a matplotlib
exporterthat lets you make
interactive, online, labels/text on the hover Plotly
graphs with matplotlib. Here is an IPython Notebook showing how to do that:

http://nbviewer.ipython.org/github/theengineear/mplexporter/blob/master/notebooks/PlotlyTest.ipynb?create=1

We're early on still, and Jake is definitely the driving force/mastermind
behind the project. We're hoping to support more and more plotting from
matplotlib and would love help, tips, feedback, and suggestions. We're
happy to talk more if you'd like.

Thanks a bunch,
M
