Can't get colormap to work properly about joypy HOT 4 CLOSED

Hello,

I ran into the same problem while trying to run on Python v2.7.13. I posted it to Stack Overflow and was presented a work-around (https://stackoverflow.com/questions/46717394/demo-of-joypy-joyplots-in-python-not-working). It's the addition of from __future__ import division to the top of joyplot.py. Obviously, the intention of this project isn't to support every version of Python, but this hack allows me to use this awesome package!

The suggestion proposed in stackoverflow makes sense. I'll add a few imports to the next release to get it working also in python 2.7.

Hi! Could you include a minimal working example? I can't reproduce the issue.

Indeed your fix would only work with what matplotlib calls "qualitative colormaps" (see here).
Continuous colormaps (sequential, diverging) don't have the "colors" attribute. Right now the colormap is called with a value between 0 and 1. That should work for all kinds of colormaps, continuous or not.

If the number of subplots is <= the number of available colors, that's what you should get (this is created with cm.tab20c):

The only issue I see with the current approach is that you might get repeated colors with qualitative colormaps that have a smaller number of colors with respect to the number of subplots. E.g., with cm.tab10, you can get something like this:

which is probably undesirable. But it doesn't seem to be your problem.

Hi @leotac

I have an issue with using the colormaps when the hist=True.
When using histograms instead of the density estimators, the colormap argument is completely ignored.
