title: Demo of Joypy (joyplots in python) not working?
body: <p>I'm working off the NBA example in: <a href="http://sbebo.github.io/blog/blog/2017/08/01/joypy/" rel="nofollow noreferrer">http://sbebo.github.io/blog/blog/2017/08/01/joypy/</a></p>
  
  <p>I follow the instructions, but my plot does not have the proper colormap. Every one of my histograms is the lowest value on the colormap (yellow in this case). Any suggestions?</p>
