[Matplotlib-users] xlabel vertical positioning

[Thomas R. <tho...@gm...>]

Hi,

This is probably a simple question, but what is the best way to  
control the vertical positioning of the x-axis label? I tried:

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as mpl

fig = mpl.figure()
ax = fig.add_subplot(111)
ax.set_xlabel("Hello",position=(0.5,-0.2))
fig.savefig('test.png')

But this doesn't work. Strangely, changing the first position element  
does shift the label left and right, but changing the second does not  
move the label vertically.

I'm using matplotlib 0.98.5.2

Thanks for any advice!

Thomas
