[Matplotlib-users] Text overlapping in mplot3d legends

[Luis Q. <l.q...@4c...>]

  Dear all,

Is there a way of avoiding the overlap between the text of the labels 
and the text of the ticks?     This is what I am getting:

     http://4c.ucc.ie/~lquesada/tmp/surface.pdf

Currently I am only doing this:

     ax.set_xlabel('Distance',fontsize=16)
     ax.set_ylabel('Size',fontsize=16)
     ax.set_zlabel('Cost',fontsize=16)

Is it also possible to give an orientation to the labels? It would be 
nicer if they are oriented parallel to the axis..
Thanks in advance for your advice!
Cheers,
Luis
