Hi Eric,
thanks for the reply.

Oh, ok, now it's clear

 and error is typically needed; it can be facilitated by using the  subplot
 adjuster widget in an interactive window (second to last button on the
 toolbar) to decide what looks good.  Then use the figure.subplot.* entries

Yeah, I used this to find 0.13 to be my number...

 in matplotlibrc, or call plt.subplots_adjust(bottom=0.15) (for example), or
 call it as a method of the figure you have just created.

...that I added this command and it worked.

 For doing the interactive adjustment, you will want to use a smaller figure
 dpi, something to match your screen.  Everything will scale correctly when
 you save the figure at higher dpi.

luckily, even at dpi=300, the image still fits my screen :)

 Hi!
 I have this configuration file:
 
 $ cat matplotlibrc
 figure.figsize   : 4, 3
 figure.dpi : 300
 savefig.dpi: 300
 font.size  : 9.0
 
 and using this code
 
 import matplotlib.pyplot as plt
 plt.plot([1, 2, 3])
 plt.xlabel('This is the X axis')
 plt.ylabel('This is the Y axis')
 plt.savefig('7900_02_06.png')
 
 I obtain the attached image that, as you can see, has xlabel tect cut.
 
 What is the best way to avoid it? reducing the actual plot area
 (axes and line)? or reducing the font size?
 
 Now that I look better at it, isn't it a bug after all? I see ylabel
 correctly rendered, and xlabel not (but it's late in the night, so I
 might be mistaken :) ) .

It is not really a bug; it is an inherent limitation in mpl's default 
automatic Axes positioning.  Axes positions are given in normalized 
coordinates relative to the figure, so if you shrink the height of the 
figure (relative to the default, for which the default positioning 
parameters are designed), there is less physical space available for the 
x-axis ticks, ticklabels, and label--and things can get cut off.  If you 
are adjusting the figsize and/or the font size, then chances are you
