Matt,

Try "my_3d_axes.set_axis_off()".  I should probably override set_visible()
to work as expected...

Hmmm, try putting that call right after the add_subplot() call.  I don't
have time to test it out right now, but I wonder if the axes are being drawn
once prior to the call to set_axis_off().  I would also be interested to
know if the axes disappear when you interact with it.

I see the same thing here (from within ipython -pylab), and moving the  
ax.set_axis_off() immediately after the add_subplot call doesn't  
change anything.  Interacting with the plot doesn't change anything  
either.

I tried Joe's code, with the call to ax.set_axis_off() moved to right after
add_subplot(), as Ben suggested. The axes are still not disappearing, nor do
they disappear when I interact with it (by rotating the plot).

Interestingly, things work perfectly with the latest build from guithub.
Presumably the bug was fixed already?

Uhm, sure!  I totally intended for that nasty bug to be fixed for the
upcoming release... <_<

Seriously, though, I made many changes to mplot3d as a part of my
refactoring efforts.  I would not be surprised if things magically break or
get fixed because of it.  I am glad you can confirm that the latest build
works.  I will take a peek at the v1.0.1 branch and see if there is an
obvious fix for them.

Ben Root

Thanks Ben, I for one would be very interested in any workarounds you might
find that don't require an upgrade from 1.0.1.
