[yt-users] time_series_phase plots & missing color bars

[Matthew Turk]

Hi Robert,

For the first issue, it looks like the profile is simply empty.  My
guess is that you've supplied some bounds, inside which no matter
falls.

For the second issue, make sure that at the top of your script you have:

import matplotlib.colorbar as cb

(like in the recipe:
http://yt.enzotools.org/doc/cookbook/recipes.html#multi-plot-3x2 )

Let us know if there's anything else,

Matt
