matplotlib-users Mailing List for matplotlib

Hi,
I had the same problem.
I solved it by using TeX, i.e., rc('text', usetex=True) for all the text
in a plot.

The linestyles can be obtained as the keys of the
matplotlib.lines.lineStyles dictionary; the markers are the keys of
the matplotlib.lines.lineMarkers dictionary
 In [95]: matplotlib.lines.lineStyles.keys()
 Out[95]: ['None', '--', '-.', '-', 'steps', ':']
 In [96]: matplotlib.lines.lineMarkers.keys()
 Out[96]: [0, 1, 2, 3, '+', ',', '.', '1', '3', '2', '4', '<','>', 
 'None', 'D', 'H', '_', '^', 'd', 'h', 'o', 'p', 's', 'v', 
 'x', '|']
The list of valid colornames are the keys of the
matplotlib.colors.cnames dictionary
 In [97]: import matplotlib.colors
 In [98]: colors = matplotlib.colors.cnames.keys()
 In [99]: len(colors)
 Out[99]: 139
 In [100]: colors.sort()

Hi list,
I'm having some font weirdness using matplotlib 0.87.4 on MacOSX with 
the WXAgg backend.
It's a clean install of universal builds from macpython.org.
First of all, when lauching for the first time (or if I delete the 
font cache), I get:

Then, if I try to save a plot in eps, nor Preview.app nor Illustrator 
can open the eps file. Furthermore the file is huge (several MB) for 
a very simple plot.
If I save the plot as a svg, then I can open the file with Firefox or 
Illustrator, although Illustrator complains about a "missing font" 
and substitute it with its defaut font. I've looked onto the svg file 
and it should use Lucida Grande, which is available on the system...
I've read on this very list that I might solve some issues by putting 
the Bitstream familly of fonts as first choice in my matplotlibrc, 
which I did.
In these conditions, saving as eps yields a file which can be opened 
by Preview.app, but opening it in Illustrator results in a plot where 
every fonts are replaced by little boxes (see attached picture)

i've gone something similar using separate masked arrays on my data set,
see
http://www.scipy.org/Cookbook/Matplotlib/Plotting_values_with_masked_arrays, for how to do this.
