Re: [Matplotlib-users] Plotting with more than two y-axes (with twinx?)

[Matt S. <ma...@pl...>]

Hi Dani,

A quick thought. You could do an interactive multiple axes graph with
Plotly, either with the Python API <http://plot.ly/api/python> or from the
GUI. Here's an example of how to re-make that one with Plotly and IPython.

The Notebook is here <http://nbviewer.ipython.org/gist/cparmer/7685051> (and
a Notebook here <http://nbviewer.ipython.org/gist/cparmer/7628933> demos
multiple axes, subplots, and insets).

Let me know if I can help with anything. Also, disclosure: I'm on the
Plotly team.

All my best,
Matt
