Unexpected keyword argument 'basex' when following the Getting Started base-2 log scale example

• Python version: Python 3.10.1 (v3.10.1:2cd268a3a9, Dec 6 2021, 14:28:59)
• Numpy Version: 1.21.5

Description

Working through the Getting Started section, on the second example with base-2 log scales, I get the following error:

TypeError: LogScale.__init__() got an unexpected keyword argument 'basex'

Changing basex to base resolves the issue.

What I Did

import numpy
from matplotlib import pyplot as plt
from scipy import stats
import seaborn

clear_bkgd = {'axes.facecolor': 'none', 'figure.facecolor': 'none'}
seaborn.set(style='ticks', context='talk', color_codes=True, rc=clear_bkgd)

fig, (ax1, ax2) = plt.subplots(nrows=2, figsize=(8, 3))
ax1.set_xscale('log')
ax1.set_xlim(left=1e-3, right=1e3)
ax1.set_xlabel("Base 10")
ax1.set_yticks([])

ax2.set_xscale('log', basex=2)
ax2.set_xlim(left=2**-3, right=2**3)
ax2.set_xlabel("Base 2")
ax2.set_yticks([])

seaborn.despine(fig=fig, left=True)

plt.show()

Open the Getting Started section at the linked built-in Matplotlib scales example and compare the base-2 example with the reported Matplotlib error. Update the outdated keyword and verify that the example runs without the unexpected-keyword exception.
