Description
Bug summary
Although the documentation says that all Line2D kwargs should be supported, only a small handful actually are:
matplotlib/lib/matplotlib/axes/_axes.py
Line 3393 in 4f5cacf
markerfacecoloralt is not among that list.
Code for reproduction
import numpy as np
import matplotlib.pyplot as plt
# example data
x = np.arange(0.1, 4, 0.5)
y = np.exp(-x)
# example error bar values that vary with x-position
error = 0.1 + 0.2 * x
fig, ax = plt.subplots(1, 1)
ax.errorbar(x, y, yerr=error, fmt='-o', markerfacecoloralt='white')
ax.set_title('variable, symmetric error')Actual outcome
AttributeError: 'LineCollection' object has no property 'markerfacecoloralt'
Expected outcome
No error
Additional information
markerfacecoloralt needs to be added to this list:
matplotlib/lib/matplotlib/axes/_axes.py
Line 3393 in 4f5cacf
Better yet, automagically check against the signature of Line2D.
