Description
Bug report
Bug summary
Axis labels and ticks are being over plotted, i.e. plotted more than once when using ParasiteAxes and subplot host. This causes the output to appear bold along certain axes.
Code for reproduction
Modified version of https://matplotlib.org/mpl_toolkits/axes_grid/users/overview.html to demonstrate location of over plotting.
from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import matplotlib.pyplot as plt
host = host_subplot(111, axes_class=AA.Axes)
plt.subplots_adjust(right=0.75)
par1 = host.twinx()
par2 = host.twinx()
offset = 60
new_fixed_axis = par2.get_grid_helper().new_fixed_axis
par2.axis["right"] = new_fixed_axis(loc="right",
axes=par2,
offset=(offset, 0))
par2.axis["right"].toggle(all=True)
host.set_xlim(0, 2)
host.set_ylim(0, 2)
host.set_xlabel("X-Overplotted")
host.set_ylabel("Y-Overplotted")
par1.set_ylabel("Axis is fine")
par2.set_ylabel("Axis is fine")
p1, = host.plot([0, 1, 2], [0, 1, 2])
p2, = par1.plot([0, 1, 2], [0, 3, 2])
p3, = par2.plot([0, 1, 2], [50, 30, 15])
par1.set_ylim(0, 4)
par2.set_ylim(1, 65)
host.axis["left"].label.set_color(p1.get_color())
par1.axis["right"].label.set_color(p2.get_color())
par2.axis["right"].label.set_color(p3.get_color())
plt.draw()
plt.show()Actual outcome
As expected the x-axis and the left hand y-axis is bold due to over plotting.
This is also seen in the figure in the documentation from
https://matplotlib.org/mpl_toolkits/axes_grid/users/overview.html#axisartist-with-parasiteaxes
Expected outcome
This appeared to work fine in Matplotlib 1.4.2

Thank you, in advance :)
