I want to update matplotlib errorbar plotting as some input data varies. The code at:

#4556

doesn't seem to work with matplotlib 2.0.0 (works fine with version 1.5.2rc2). Hints? Thanks!!

Code for reproduction

For example:

import numpy as np
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
x = np.linspace(0, 2*np.pi, 15)
y = np.sin(x)
y_err = np.cos(x) * 0.1
err = ax.errorbar(x, y, y_err)
ln, (err_top, err_bot), (bars, ) = err

Actual outcome

returns the following erro:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: need more than 0 values to unpack

It used to work on 1.5.2rc2 and python 2.7.12.
