[yt-users] Error with annotate_marker: Unknown property

[Nathan Goldbaum]

Hi Chao,

For that callback, you're only allowed to specify keyword arguments
accepted by matplotlib.axes.Axes.scatter:
http://matplotlib.org/api/axes_api.html#matplotlib.axes.Axes.scatter

or Collection properties:
http://matplotlib.org/api/collections_api.html#matplotlib.collections.Collection

I'd have to look closer to figure out which keyword corresponds to what
you're looking for, but hopefully that leaves you enough information to
figure out how to do what you're trying to do.
