Comment (by jhpalmieri):
The "doctest" syntax for matplotlib's plot directive sounds interesting:
{{{
3. Using **doctest** syntax::
.. plot::
A plotting example:
>>> import matplotlib.pyplot as plt
>>> plt.plot([1,2,3], [4,5,6])
}}}
but I can't figure out how to get it to work, mainly because I don't know
how to convert a Sage graphics object into something matplotlib can plot.
For example,
{{{
sage: C = grsphs.PetersenGraph().plot()
sage: fig = C.matplotlib() # looks good, right?
sage: fig.show()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call
last)
...
AttributeError: 'NoneType' object has no attribute 'manager'
Figure.show works only for figures managed by pyplot, normally created by
pyplot.figure().
}}}
Understanding how to do this would let us use just a few lines like
{{{
.. plot::
>>> from sage.all_cmdline import *
>>> graphs.CubeGraph(8).plot().matplotlib().show()
}}}
instead of having to manually save to a temporary file.
