Bug report

Bug summary

When using variable colors for error bars, the colors are incorrect/shifted if NaN values are present.

Code for reproduction

import numpy as np
import matplotlib.pyplot as plt

x = [1, np.nan, 3, 4, 5]
colors = ['red', 'green', 'blue', 'purple', 'orange']

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
ax.scatter(x, x, c=colors, s=100)
ax.errorbar(x, x, xerr=0.2, yerr=0.2, ecolor=colors, fmt='none')
fig.savefig('errorbar_colors.png')

Actual outcome

errorbar_colors

Expected outcome

errorbar_colors
