Changing the display angle of tick_labels?

Hello, Is it possible to change the angle at which tick

Hi Mike, take a look at the FAQ "How do I make vertical xticklabels?"

and the general tutorial on working with text which shows how
to set text properties. One of the properties is rotation, which can
be applied to any text instance (title, ticklabel, xlabel, etc.)

Rotation can be 'horizontal', 'vertical' or an angle in degrees. Not
all backends support the latter, but the *Agg backends should and it
would not be too much work to add this to PS and GD. Let me know if
you need it.

Safest for you if you need this across backends would be 'vertical'.
