   Hello!
  I have noticed several days ago that when I use the
    my_plot.show(xmin=0, ymin=0, frame=True)
to show my plot, I get an image with slightly misplaced surrounding box
boundaries relatively to X and Y axes. They should be at X=0 and Y=0
(in fact, the box boundaries should coincide with the axes in such
case), but they are not.
  Here is a sample image:

  How can I fix this behaviour?
  Thank you.
    Vladimir

  P.S. I'm not sure whether this issue is Gentoo-specific or not,
that's why I decided to ask here first.

Hi Vladimir,

Has it started after your upgrade to sage-4.8? I'll have to check but 
Jason did some work around the default settings for matplotlib.
That may be a consequence.

  I'm not completely sure whether it started only with Sage 4.8. I have
noticed it only recently. Perhaps, on Monday I will have an access to
Sage-4.7 machine and check it out.
  But what I have noticed today is that the distance between the box
edges and major ticks on axes depends on the figure size, and not on
the font size like I thought previously. 
  See for example, this published worksheet:

  Hello!
  Today I checked this issue on the university machine with Ubuntu and
Sage 4.7. The problem is already there. So it is unlikely to have
appeared in 4.8 only.
