Axes label rotation

[narasimhaprasad]

Axes labels are not parallel to the tick label, making the plot look as if it has been rotated.

Eg:

When the text is short, we don't rotate the axes label in the same way as
for longer labels. To get around this, just put a few extra spaces before
and after the text. I don't have the docs in front of me to remember if
there is a keyword argument to override this naturally.

Weather God : Sorry, I added a ton of spaces. but could not get it to orient vertically. I am also unable to find the keyword argument to enable it. And I think you misunderstood my query. I am trying to point out the fact that axis and the axis label are not parallel.

[WeatherGod]

Are you referring to the tick labels? Besides the z-axis label and the
title, the tick labels are the only things in that image that doesn't line
up with the axis.

If that is the case, there is no mechanism for turning that on right now.
It shouldn't be too hard to add, though.

For example 'Torque' is not parallel to the tick labels [(0, 0.5 1, 1.5, 2.0)]. Same issue with 'Speed'

[WeatherGod]

Which version of matplotlib? This was fixed a few releases ago.

[narasimhaprasad]

The latest 1.3.0.

Next time, please provide a completely self-contained example. The example provided did not have everything defined.

The image I get is the same as the one you posted, and I still don't understand. Take a look at the following simplified example (quickly pulled from an internal test script of mine):

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

ax.set_ylim(1, 0)
ax.set_xlabel('XXXXXXXXXXXXXXXXXXX')
ax.set_ylabel('YYYYYYYYYYYYYYYYYYY')
ax.set_zlabel('ZZZZZZZZZZZZZZZZZZZ')
plt.show()

The axes labels line up perfectly parallel to the axes line. So, perhaps I am still not understanding the issue you are seeing? Perhaps you want the tick label text to be parallel like the axes label text?

@narasimhaprasad If this is still an issue please ping to have this re-opened.
