in yout LaTeX document, the alignment of text elements in imported figures
may be off. Check the header of your ``.pgf`` file if you are unsure about
the fonts matplotlib used for the layout.


* Vector images and hence ``.pgf`` files can become bloated if there are a lot
of objects in the graph. This can be the case for image processing or very
big scatter graphs. In an extreme case this can cause TeX to run out of
memory: "TeX capacity exceeded, sorry" You can configure latex to increase
the amount of memory available to generate the ``.pdf`` image as discussed on
`tex.stackexchange.com <http://tex.stackexchange.com/questions/7953>`_.

For rst reasons I only half understand, using 2 __ for the link is safer. Ditto 3 lines down.

Another way would be to "rasterize" parts of the graph causing problems
using either the ``rasterized=True`` keyword, or ``.set_rasterized(True)`` as per
`this example <http://matplotlib.org/examples/misc/rasterization_demo.html>`_.
