Setting markeredgecolor raises a warning #6480
Description
Hi matplotlib developers,
Setting markeredgecolor to an RGB or RGBA numpy array now gives a warning in matplotlib 1.5.1. This was not a problem in version 1.4.3. Here is a minimal working example:
import numpy as np
import matplotlib.pyplot as plt
# color = [0.5, 0.5, 0.5, 1.0] # Works without a warning
color = np.array([0.5, 0.5, 0.5, 1.0]) # Gives a warning
plt.figure()
plt.plot(np.arange(9), np.arange(9), marker='o', markeredgecolor=color)
plt.show()In python 2.7, it gives this warning:
/usr/lib/python2.7/site-packages/matplotlib/lines.py:1082: UnicodeWarning: Unicode unequal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
if self._markeredgecolor != ec:
And in python 3.5, it gives this different warning:
/usr/lib/python3.5/site-packages/matplotlib/lines.py:1082: FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison
if self._markeredgecolor != ec:
Tested on Arch Linux.
--Thanks.
