setting ticks on Axes3D

Hello list, I am trying to set ticks on an Axes3D plot.
What I really want is, actually, not to have any ticks.
For a 2D plot I set the ticks to an empty list.
But in a 3D plot, I cannot set any ticks whatsover.
At least not with a sequence.
Any thoughts?

from mpl_toolkits.mplot3d import Axes3D

fig = figure()

ax = Axes3D(fig)

ax.plot([0,1],[0,1],[0,1])

Now I want to set ticks:

ax.set_xticks([])

ax.set_xticks([.2,.3,.4]) # changes the scale of the figure, but not the ticks

show()

And the plot has ticks at .2 .4 .6 .8 on the x-axis.

Thanks for any help,

Mark
