Sami,
I did take a quick peek at the code to assess how much effort it would take
to make it work properly. It isn't trivial, to say the least, because the
user-supplied rotation value is overwritten in order to do the 3d-managed
rotation. This is actually similar to another problem where user-supplied
colors to scatter plots would be over-written as one interacts with the
plot.
I have a possible quickfix in mind, but I have to test it out, and I
already know of some edge cases where it won't work. But it might be
sufficient for most use-cases.
Cheers!

Still not working. The output looks like this:
File "NotasFaltasdoisgraficos.py", line 58
  ax3.axvspan(*mdates.datestr2num(['05/18/2012', '06/30/2012']), facecolor='g', alpha=0.5)
                                                              ^
SyntaxError: invalid syntax
When you say "...change the months to short English form" you mean in the data file?
That is, Abr -> Apr, Mai -> May??? ...still did not work.

Subject: Re: [Matplotlib-users] axvspan with dates on x-axis
 
Looks like your very close.
I needed to change the months to short English form, change the line
 ax3.grid('True') to ax3.grid(True)
and add the line
 ax3.axvspan(*mdates.datestr2num(['05/18/2012', '06/30/2012']),
facecolor='g', alpha=0.5)
To get the box on the lower plot.
Hope that helps,

Thanks Ben for your explanation. I have filed a feature request:

Because mplot3d has to managed the rotation of the axes label text itself,
it over-rides any user-specified rotations. I guess it is feasible to
apply a rotation on top of the internal rotation. Could you file a feature
request on github for this?

Hi, 
I have not managed to rotate the axes label text when generating a 3D plot, while in 2D everything works just fine. Here's a short snippet to demonstrate:
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.set_zlabel('label text flipped', rotation=45)
ax.azim = 225
plt.show()
I've tried other commands like:
ax.w_zaxis.set_label_text(r'$\left ( \frac{R}{R_{ref}} \right )^{2}$', rotation='vertical')
without success. I would prefer not to use a solution like "pathpatch3d_demo.py" because then I need to find the location separately. Any suggestions?
Cheers,
Sami
