If I try to format the text using tex in a figure where a colorbar is
present, I get the following error:

I am using the MacPorts installation of matplotlib on OS X 10.9.  I can
generate this error by adding the line:
plt.rc('text', usetex=True)

to any example code that has a colorbar, (i.e., griddata_demo.py).  The
consequence of this error is that the figure does not have any text on the
colorbar axis.

Thanks for your answer. I have been struggling with this for many days...

Unfortunately, no, it isn't possible (at this time). I really should add
code that would raise a NotImplementedError when those methods are called.
The problem is primarily with how the position of the axis labels are
determined while one rotates the 3d plot area. I would need some sort of
flag to indicate that an axis is a twinned axis so that the "other"
position is used (and fix a whole bunch of other code that makes certain
positioning assumptions). Not impossible to implement for the
brave-hearted, but it isn't possible to jury-rig or work around right now.

Hi,

Is it possible to create multiple y,x axis for a 3D plot?  

I tried to create the secondary axes with ax.twinx() but I don't know how to
get the right orientation.

I would appreciate any help

Monica
