plot_average_pulses() and plot_filters() not working

Going against master, neither plot_average_pulses() nor plot_filters() are working for me. I don’t know whether this is really a bug in MASS, or a problem with my setup.

Here are the errors:

In [3]: data.plot_average_pulses()

I get the same error. I’m sure it’s some change in matplotlib. I’ll work on it.

Remove all color=[x] usage

This was all an error in understanding newer matplotlib, similar to the #186 issue. Fixes #186.
