I think this is a bug in Axis3D. In the meantime, one can use

# make ticklabels and ticklines invisible
for a in ax.w_xaxis.get_ticklines()+ax.w_xaxis.get_ticklabels():
    a.set_visible(False)

Note that w_xaxis, w_yaxis, w_zaxis correspond to x, y, z axis.
To remove y tickmakes, replace ax.w_xaxis with ax.w_yaxis.

host.axis["left"].major_ticklabels.set_size(24)

or

host.axis["left"].label.set_size(24)

should work.

On the other hand, if you're using matplotlib v1.0 or later, I
recommend you to use "axes_grid1" instead of "axes_grid". With
axes_grid1, set_xlable and set_ylable work as expected. For example,
your code can be something like below.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1.parasite_axes import HostAxes

fig = plt.figure()
host = HostAxes(fig,[0.08, 0.1, 0.82, 0.83])
fig.add_axes(host)
par = host.twinx()
host.set_xlabel('Dominant Characteristic Threshold', size=24)
host.set_ylabel('Number of Groups', size=24)
par.set_ylabel(' Noise Students', size=24)

# bunch of plot commands

host.set_ylim(0,8)
par.set_ylim(0,0.9)

I'm creating a twined axes figure and have run into a problem.  I need 
to increase the font size of all the text on the plot, but nothing I do 
seems to work.

Here's the code I have to generate the plot:

Things I've tried:
Adding a size keyword argument to the set_xlabel and set_ylabel commands 
(both numerical and keywords).  No errors are raised, but nothing is 
changed on the plot.

Adding host.axis["left"].set_size(24) and 
par.axis["right"].set_size('large'), to the code.  This raises an 
AttributeError: 'AxisArtist' object has no attribute 'set_size'

Adding host.set_size(24) and par.set_size('large') to the code.  This 
raises an AttributeError: 'AxesHostAxes' object has no attribute 'set_size'

Any suggestions for how to get the font size larger?

I have done some further research on this, and it appears to be a bug of
some sort.  Possibly the Locators are already made by the time the
ax.set_xticks([]) is called and that function falls on deaf ears because the
real xaxis is actually a different object for Axes3D.  When trying to dig
down and force zero ticks from being used (using NullLocator), I get errors
when attempting to draw:

All of the text commands "text", "xlabel", "ylabel", "title" take a
rotation keyword argument, so you can pass that in and set the angle
you want.  With an existing text instance, you can call the
set_rotation method.

Here is a demo that shows some of the rotation modes

Hi,

I'm pretty new to Matplotlib and I'm really impressed about the
possibilities !!!
GREAT WORK !!!

I have a figure with 3 subplots like this.

*-------*    *------------------------------*

I want to have the text on the x-axes rotated, but only for subplot A and B
The text for subplot C should remain unrotated.

Is that is possible?

Best regards,
Thorsten
