Issue #745: Can't pl.plot(YTArray, YTArray) (yt_analysis/yt)
New issue 745: Can't pl.plot(YTArray, YTArray) https://bitbucket.org/yt_analysis/yt/issue/745/cant-plplot-ytarray-ytarray Sam Skillman: ``` #!python from yt.mods import * import matplotlib.pyplot as plt a = YTArray([1.0,2.0]) plt.plot(a, a) ``` produces: ``` #!python (yt-x86_64)360Mpc/1024L0:python test_plot.py Traceback (most recent call last): File "test_plot.py", line 6, in <module> plt.plot(a, a) File "/u/ki/skillman/yt-x86_64/lib/python2.7/site-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/pyplot.py", line 2987, in plot ret = ax.plot(*args, **kwargs) File "/u/ki/skillman/yt-x86_64/lib/python2.7/site-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/axes.py", line 4137, in plot for line in self._get_lines(*args, **kwargs): File "/u/ki/skillman/yt-x86_64/lib/python2.7/site-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/axes.py", line 317, in _grab_next_args for seg in self._plot_args(remaining, kwargs): File "/u/ki/skillman/yt-x86_64/lib/python2.7/site-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/axes.py", line 276, in _plot_args linestyle, marker, color = _process_plot_format(tup[-1]) File "/u/ki/skillman/yt-x86_64/lib/python2.7/site-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/axes.py", line 80, in _process_plot_format color = mcolors.colorConverter.to_rgb(fmt) File "/u/ki/skillman/yt-x86_64/lib/python2.7/site-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/colors.py", line 291, in to_rgb argl = arg.lower() AttributeError: 'YTArray' object has no attribute 'lower' ``` Using .to_ndarray() on a in the plotting call works as expected. pl.plot(a) also works, so I think this must be something about mpl interpreting the second ytarray as a different arg/kwarg.
