Bug summary

This bug occurs when I set xlabel of axisartist.Axes to some non-empty string, and draw the figure, but when I set the xlabel to another string, the figure does not change.

Code for reproduction

import matplotlib.pyplot as plt
import mpl_toolkits.axisartist as axisartist

fig = plt.figure()
ax = fig.add_subplot(axes_class=axisartist.Axes)
ax.axis["top"].set_visible(False)
ax.axis["right"].set_visible(False)

ax.set_xlabel("first label")
fig.draw_without_rendering()
ax.set_xlabel("second label")
plt.show()
