Call subplots_adjust(hspace=0.1), etc.
This is a pylab method that applies to the current figure
 fig = figure()
 subplots_adjust(hspace=0.1)
or if you prefer a Figure method
 fig.subplots_adjust(hspace=0.1)
The default values are set in your matplotlibrc file
http://matplotlib.sf.net/matplotlibrc
 # The figure subplot parameters. All dimensions are fraction of the
 # figure width or height
 figure.subplot.left : 0.125 # the left side of the subplots of the figure
 figure.subplot.right : 0.9 # the right side of the subplots of the figure
 figure.subplot.bottom : 0.1 # the bottom of the subplots of the figure
 figure.subplot.top : 0.9 # the top of the subplots of the figure
 figure.subplot.wspace : 0.2 # the amount of width reserved for blank space between subplots
 figure.subplot.hspace : 0.2 # the amount of height reserved for white space between subplots

Hi, just to roll the ball, your code works fine for me under linux

Try the axes([left, bottom, width height]) command to manually place your 
axes.

I am having a problem saving figures with any of the Agg backends.
Below is a sample of code and the resulting output. I receive the same
type of errors with any of the Agg backends ie WxAgg, TkAgg ect. With
SVG, or GD it does save. I am running python 2.3 under windows XP
matplotlib .83.2. Can you provide some guidance as to what I may have
configured wrong with the Agg backends?
Sample code run with -dAgg
 
 
 
 #!/usr/bin/env python 
 from pylab import * 
 
 plot(arange(10), color='#006400') 
 xlabel('this is a xlabel\n(with newlines!)') 
 ylabel('this is vertical\ntest', multialignment='center') 
 #ylabel('this is another!') 
 text(2, 7,'this is\nyet another test', 
 rotation=45, 
 horizontalalignment = 'center', 
 verticalalignment = 'top', 
 multialignment = 'center') 
 savefig('c:\multiline.jpg')

Hi everyone,
When you draw a picture with subplots, you can control the vertical and 
horizontal spaces between thanks to the "configure subplots" button in 
the toolbar.
I'm sure there is a way to set the values of wspace and hspace manually 
but could'nt find it. That does not seems to be reported (yet) in the 
documentation.
any clue ?

Hi,
I really like the possibility to create labels with tex support. 
Unfortunately, using this feature, svg export seems to be no longer 
available. This is sad, because creating svg's was one of my major reasons 
using matplotlib. Using latex most of the time, it was possible to create 
high quality vector based images with the possibility to change them later 
(e.g. with inkscape). I use this feature mostly for language changings of 
labels or titles.
The error message:
Traceback (most recent call last):

Any idea, how to bring svg export back to work again ?

How do I install the missing software ?
