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()

  In [101]: colors[:5]
  Out[101]: ['aliceblue', 'antiquewhite', 'aqua', 'aquamarine', 'azure']

Darren -- something for the user's guide?

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.
