Sorting out a general way to do plotting in a figure between different axis objects is something we should probably do. This relates back to the 'spark line' (maybe have the name wrong) code that @phobson has, but rotated so that the axis spines are radial instead of lined up.

#4699 is adding a lot of improvements to polar plots. Perhaps that could be addressed there or @QuLogic has some ideas having been digging around there a lot lately.

@tacaswell are you referring to this: http://stackoverflow.com/questions/15167928/implementing-horizon-charts-in-matplotlib?

No it was something with many y axis with lines connecting them what was
used to show rough correlations between high dimensional data points.

oh oh oh ... this: https://gist.github.com/phobson/9de120cabde660ec734c

By the way -- this turns into a dumpster fire if you try to use log scales.

@phobson This plot is much better than a radar chart for my use. Thanks.

Great stuff all... I guess the question is whether we want to keep this open. The subject line of this issue is still true, however, multiple r scales on a polar plot is hard to display effectively...

At a minimum @phobson 's demo code should end up in the examples.

I can take a stab at removing the seaborn and pandas dependencies of the example over the holiday.
