I am 99% sure this is a font problem. matplotlib embeds the truetype
font into the PS file, which accounts for most of the file size. Paul
Barrett at one point looked into just embedding he glyphs we use
rather than the entire font file but was unsuccessful. It would be
nice if some font guru could revisit this issue at some point since it
would be a big win in terms of file size. What appears to be
happening is that mpl is finding and using a native os x font rather
than the Vera fonts that mpl ships with.
Try editing your matplotlib rc file and change these font preferences
font.serif : New Century Schoolbook, Century Schoolbook L, Utopia,
ITC Bookman, Bookman, Bitstream Vera Serif, Nimbus Roman No9 L, Times New
Roman, Times, Palatino, Charter, serif
font.sans-serif : Lucida Grande, Verdana, Geneva, Lucida, Bitstream Vera
Sans, Arial, Helvetica, Avant Garde, sans-serif
font.cursive : Apple Chancery, Textile, Zapf Chancery, Sand, cursive
font.fantasy : Comic Sans MS, Chicago, Charcoal, Impact, Western,
fantasy
font.monospace : Andale Mono, Bitstream Vera Sans Mono, Nimbus Mono L,
Courier New, Courier, Fixed, Terminal, monospace
by moving the bitstream fonts to the front.
I'm inclined to make the bitstream fonts the default (the first item
in the default rc list) so that others won't be bitten by this until
we solve the "dump the entire font" problem. Any objections?
Benoit, please let us know if this fixes your problem. After changing
the rc file, please recursively remove ~/.matplotlib/ttffont.cache
before rerunning. Also, if you run your script with --verbose-debug
you will get information about which fonts are loaded.
