Thanks. This fig.subplots_adjust(bottom=0.15) works well for me.

I was thinking like TeX/LaTeX, it automatic calculate the space and
overlapping between symbols (treated as boxes, forgot what Knuth call
it).

I used the rcParams before, but sometimes I plot for PPT with larger
fonts, sometimes for article with smaller fonts. the rcParams did not
worked well for me.


Best regards

I dashed that last reply off quickly - a more complete answer would 
address your local parameter settings.  In pyplot.rcParams, you can set 
the default values for a number of parameters. In this case, I believe 
the parameters that will affect the cropping are the image size and the 
sizes of the axis labels and tics. I'm fairly new to these items myself 
- I'm not convinced that changes rcParams will be preserved from one 
python session to the next.

Take a look into pyplot.subplots_adjust - you can specify buffers there 
as a fraction of the window size, e.g.
pyplot.subplots_adjust(0.155,0.12,0.95,0.9) works well for a 3.5"x3" 
figure with 8-pt font on the axis labels and tics.

Hi,

   I am embedding a plot in Qt4 application, following the matplotlib
example embeding_in_qt4.py, however I found that the xlabel is cut
off, although the label shows more if I resize the window, still it is
not the right one. Is it because of my local parameter settings or
it's the limit of the example code. How can I fix this ?

  Thanks.

Best regards,
