[Matplotlib-users] Rendering SciPy docstrings as markup text within matplotlib
Hi,
SciPy (and NumPy) docstrings are written with a special kind of mark up:
For example, the docstring for the russellrao distance function looks like
this:
'\nComputes the Russell-Rao dissimilarity between two boolean 1-D
arrays.\n\nThe Russell-Rao dissimilarity between two boolean 1-D
arrays, `u` and\n`v`, is defined as\n\n.. math::\n\n \\frac{n
- c_{TT}}\n {n}\n\nwhere :math:`c_{ij}` is the number of
occurrences of\n:math:`\\mathtt{u[k]} = i` and :math:`\\mathtt{v[k]} =
j` for\n:math:`k n`.\n\nParameters\n--\nu : (N,)
array_like, bool\nInput array.\nv : (N,) array_like, bool\n
Input array.\n\nReturns\n---\nrussellrao : double\n
The Russell-Rao dissimilarity between vectors `u` and `v`.\n\n'
What's the most efficient way to turn this into a format where you can
format it nicely as a matplotlib text object?
I tried:
fig = plt.figure()
ax = fig.add_subplot(111)
props = dict(boxstyle='round', facecolor='wheat', alpha=0.5)
textstr = dist_fcn.__doc__
textstr = textstr.replace('math:',' ')
textstr = textstr.replace('`', '$')
textstr = textstr.replace('\n\n where', '$\n\n where')
ax.text(0.05, 0.95, textstr, transform=ax.transAxes, fontsize=14,
verticalalignment='top', bbox=props)
Which does an 'ok' job, at best, since fractions aren't converted properly.
Is there a way to do it nicely short of using some horrendous regular
expressions?

Here is what I did to fix it: Remove the freetype/fontconfig rpm from my local install (yum remove) and then place the proper PKG_CONFIG_PATH to point to my remote freetype/fontconfig. By remote, you mean self-built, rather than from a package? The problem is there is a bug with setupext.py. We ought to prepend PKG_CONFIG_PATH in the gcc compile statement. I hope this helps. Can you elaborate? The setupext.py just calls whatever pkg-config is first on the PATH, which should then in turn obey PKG_CONFIG_PATH. If the user needs a custom PKG_CONFIG_PATH, it is generally the resposibility of the user to set it correctly -- and matplotlib's build system should (and does) use it.

Re: [Matplotlib-users] Rendering SciPy docstrings as markup text within matplotlib
docutils is the library that supports the format (restructuredtext) that
these docstrings are written in. It *may* (I haven't looked) contain
functionality to render as clean plain text.

Re: [Matplotlib-users] Bug in Custom Dash List
The problem is that a 0-length dash or space is undefined. In Agg, it causes an infinite loop (presumably because the line cursor never moves). Saving it to a PDF file and opening it in Acrobat Reader reveals a blank page (presumably because it's doing something smarter, but also basically throwing up its hands). In SVG, you get a solid line, which may or may not be the right behavior. Given that a value of 0 doesn't make much sense anyway, I thought it best to just disallow it.

Logically, XQuartz should not be needed at all; mpl on the mac does not require X11. It looks like XQuartz is an accidental dependency, as a way to get access to a suitable libpng. A link from the libpng web site led to this: http://ethan.tira-thompson.com/Mac_OS_X_Ports.html which might be a viable alternative. Eric -- Get your SQL database under version control now!

You'll have to re-install the security updates that came out after the combo updater was released if you use it, which is a bit of a pain. According to otool -L, the libpng12.0.dylib installed with X11 2.3.6 is version 45, compatibility version 45, so it should work with matplotlib. If you don't want to run the combo updater because of possible side effects or install XQuartz you can download libpng from http://sourceforge.net/projects/libpng/files/libpng15/1.5.17/, unpack it and do the standard ./configure, make, sudo make install to install it in /usr/local/lib. setup.py should find it there. hth, Scott If Matplotlib is only expected to work for the Quartz installs - is it worth trying to detect that and warn / error at install time?
