[yt-users] Error with annotate_marker: Unknown property

[Chao Shi]

Hi all,

I'm trying to mark some positions with circle on slice and projection plot.
But it can't recognize arguments used for specifying the property of the
marker. For example:


>>> p = SlicePlot(pf,'x','Density')

>>> p.annotate_marker([0.5]*3,marker='o', plot_args={'color': 'red', 'mew':
5})

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/cshi31/yt-x86_64/src/yt-hg/yt/visualization/plot_window.py",

AttributeError: Unknown property mew

mew is an alias for markeredgewidth. I also tried with 'markeredgewidth'
but it gave the same error.

Besides, 'mec', 'ms' also can't be recognized. Only 'color' works.

Does anyone have a clue about this?

Thanks very much.

Chao
