I'm not really sure why the configobj dependency doesn't resolve properly.
As they say: pull requests are welcome. ;)
This is all *crying out* to be dropped straight into matplotlib proper!

Here's a PR to add the style sheets from mpltools:

First let me return to the fonts issue. I had been misunderstanding the rcParams (this seems to be a recurring problem at the moment ;) - some new documentation is definitely required; I will try to get round to add it to my matplotlib.settings notebook). The fuzziness I referred to was indeed a retina issue, stemming from the fact *that the default output format is still PNG*. It seems to me that these days the default output should be SVG, which immediately resolves all retina issues!! (And a lot of other issues, it seems to me.) The current status of retina support is actually reasonable. There are two options: %load_ext retina %config InlineBackend.figure_format = 'retina' In the absence of tab completion for %load_ext and %config, and not understanding the code, I am not sure if these are synonyms or not. But the effect is to have PNGs produced with twice the vertical and horizontal resolution. (The problem comes if, for example, these are included in output sent to nbviewer, in which case they appear twice as large.) One STIX font question remains: How can I get the text of the tick labels and other things to also be in STIX? settings['font.family'] = 'stix' does not work, apparently. And could the default font finally be changed to something else? What are the licensing requirements for the font? Is it distributed with matplotlib, or how does it work?

Re: [matplotlib-devel] How to use STIX fonts in matplotlib plots?
Breaking news from the MathJax site: The *SVG output processor* is new in MathJax version 2.0, and it uses Scalable Vector Graphics to render the mathematics on the page. Mike: Could we use this to finally render all text in STIX *without* using an external TeX installation? This would be fantastic!

[matplotlib-devel] No plot output when running a script from another script
I am trying to execute (with execfile) a script A.py containing matplotlib
plotting commands from within a script B.py.
Within B.py, I do execfile("A.py")
The A.py script runs correctly, except that no plot is shown.
I have checked that the A.py script does plot (to a separate window) when
run
with python A.py from the terminal.
A.py does include plt.show()
Could an expert on backends help, please!
Thanks
David.

Hello, I was just wondering what is wrong with using the name rc (because it's just a convention how to name your variable)? It is still used quite widely on UNIX (and Mac OS is still a UNIX :)). Also, it is documented here: http://matplotlib.org/users/customizing.html I see your point though, in this document there isn't a single word, that the 'rcParams' stand more or less for the parameters which are initialised when matplotlib loads or starts plotting. Do not know if we should change this page to add some explanation, why we use *rc settings*.

There is a very good way to use otf and ttf fonts in LaTeX and matplotlib, which you might like: http://matplotlib.org/users/pgf.html With this method you can use LuaLaTeX, or XeLaTeX, both of which have options to load OTF or TTF fonts. This would be done via the LaTeX preamble in the .matplotlibrc file, which might be storred in the home directory on your Mac (just a guess, since I do not normally use matplotlib with a Mac). This might be a bit of a steep learning curve if you haven't done anything more serious with matplotlib, but you won't have to install the fonts, which, I must agree, *is* painful.

David,
The attached scripts, which seem to be a minimal example of what you
describe, work for me with matplotlib 1.2.1, MacOSX backend.

The advantage of png is that although it is not optimal from a visual standpoint, it works reliably and predictably with everything. Therefore it is a sensible default.
