Hi,
Does the zorder work between twin axis? I can't get lines on the first axis to be on top of the second grid:
plot([20,30], [0, 5], color="red", lw=5, zorder=10)
ax2=twinx()
grid(ls="-", lw=5, zorder=-1)
ax2.set_axisbelow(True)
title("Why doesn't the read line go above the second axis?")
Cheers,
Olle
twinx makes a separate axes and zorders are only meaningful within a same axes.
Because ax2 is added to the figure later than the original axes,
artists in ax2 are always above others.
I don't think there is an easy way to make zorder work between several
axes, unless you somehow merge them into a single axes. You may try my
(a bit experimental) helper class made for this purpose.

import matplotlib.pyplot as plt
from parasite_axes2 import SubplotHost
f = plt.figure(2)
ax = SubplotHost(f, 1, 1, 1)
f.add_subplot(ax)
ax.plot([20,30], [0, 5], color="red", lw=5, zorder=10)
ax2=ax.twinx()
ax2.grid(ls="-", lw=5, zorder=-1)
ax2.set_axisbelow(True)
plt.show()
