This is a bug in the axes_grid toolkit. As a matter of fact, gridlines
in rectlinear coordinate are not implemented yet.
Unfortunately, I don't see any easy workarounds.
You may use mpl's original axis artists, but some of the functionality
of axes_grid toolkit may be lost.
host.toggle_axisline(False)
host.yaxis.set_ticks_position("left")
host.yaxis.grid()
host.set_yscale("log")
With new spine support in mpl, I think a similar plot can be drawn
without using axes_grid toolkit.
