[yt-dev] cookbook recipe plot error

This recipe's plot:

http://yt-project.org/docs/dev-3.0/cookbook/calculating_information.html#tim...

has information from a different plot overplotted (in fact, it is this recipe's last panel:

http://yt-project.org/docs/dev-3.0/cookbook/complex_plots.html#styling-radia...

So something is not being reset between recipes as part of the doc build that runs all the recipes. Nathan suggested that perhaps the script that run's the recipes needs a plt.close() in it. Alternately, we can all plt.clf() to receipes one at a time, but that seems less optimal.

If someone knows better how the receipes are run, can they look at this?
