Dear Michael,
I deeply appreciate your help with this!

I have tried
import matplotlib

as you suggested, but they had no effect whatsoever. Even the error
output is the same.
I'm surprised that isn't having any effect. The Cairo backend should not
be running any code in backend_ps.py -- where the source of the error
is. If you put "backend: GtkCairo" in your matplotlibrc, does that work?
No, in fact, after adding that line to matplotlibrc the CJK isn't even
rendered in the png anymore! *
My error message has changed:
In [1]: run dea.py
/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:614:
DeprecationWarning: Use the new widget gtk.Tooltip
self.tooltips = gtk.Tooltips()
(this with "backend: GtkCairo" in matplotlibrc and the following two
lines in my dea.py:
import matplotlib
matplotlib.use('GtkCairo')
Incidentally, if I uncomment those two lines, then the (Western) font of
my graph actually changes.
What version of matplotlib are you running?
In [2]: matplotlib.__version__
Out[2]: '0.99.0'
Note: in line 327 and 328 of the matplotlibrc I have added
ps.fonttype=42
pdf.fonttype=42
I haven taken those out again, because I got an error message.
I continue to be at a loss!

* I had the same problem yesterday, I solved it by reinstalling a backup
of matplotlibrc. Weird.
whereas I have uncommented
pdf.fonttype : 3
Any ideas? I would most welcome any hint and suggestion!
I don't think these settings will resolve the problem -- either font
type (42 or 3) still expects glyph names.

The font you are using (SimHei) does not have any glyph names -- these
are used in the Postscript backend to refer to glyphs outside of the
ASCII range. More specifically, it looks like it has at least one
invalid glyph name (glyph names can only contain ASCII characters) --
loading it in FontForge complains about this. I haven't come across such
a font before, but maybe that's common in CJK fonts. I don't know. I'm
looking through the spec to find a way that glyphs can be referenced
without a name, but I'm not finding one. Note, the PDF backend has the
same issue.
Do you have the same problem if you remove "SimHei" from the
font.sans-serif list and thus use "Adobe Song Std" instead? (I was able
to find an online download of SimHei to test with, but not Adobe Song
Std).
As a workaround, the Cairo backend seems to handle this font just fine.
You can add
import matplotlib
matplotlib.use('GtkCairo')
to the top of your script.

Hello everybody,
I have a final problem with my graph. As a last step I produce an
*.eps file that I use in conjunction with LaTeX.
Here is the last part of my code:
# plt.title('Title')
xlab = plt.xlabel(u'输入 1')
#xlab.set_position((0.2, 0.1))
ylab = plt.ylabel(u'输入 2')
plt.grid(True)
plt.subplots_adjust(bottom=0.2)
plt.show()
plt.savefig('dea.eps')
plt.show() produces the correct output,
but
plt.savefig('dea.eps') produces an error (the error message is
attached).
The error is clearly linked to the Chinese, as it runs through if I
take the Chinese out of the code.
Also, plt.savefig('dea.png') works fine.
Could anyone indicate where I would have to look for the mistake? The
matplotlibrc should be fine, but I am not sure.
Your help would be greatly appreciated!
Many thanks,
David

### MATPLOTLIBRC FORMAT
# This is a sample matplotlib configuration file - you can find a copy
# of it on your system in
# site-packages/matplotlib/mpl-data/matplotlibrc. If you edit it
# there, please note that it will be overridden in your next install.
# If you want to keep a permanent local copy that will not be
# over-written, place it in HOME/.matplotlib/matplotlibrc (unix/linux
# like systems) and C:\Documents and Settings\yourname\.matplotlib
# (win32 systems).
#
# This file is best viewed in a editor which supports python mode
# syntax highlighting. Blank lines, or lines starting with a comment
# symbol, are ignored, as are trailing comments. Other lines must
# have the format
# key : val # optional comment
#
# Colors: for the color values below, you can either use - a
# matplotlib color string, such as r, k, or b - an rgb tuple, such as
# (1.0, 0.5, 0.0) - a hex string, such as ff00ff or #ff00ff - a scalar
# grayscale intensity such as 0.75 - a legal html color name, eg red,
# blue, darkslategray
#### CONFIGURATION BEGINS HERE
# the default backend; one of GTK GTKAgg GTKCairo CocoaAgg FltkAgg
# MacOSX QtAgg Qt4Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG Template
# You can also deploy your own backend outside of matplotlib by
# referring to the module name (which must be in the PYTHONPATH) as
# 'module://my_backend'
backend : TkAgg
#backend : GtkCairo
# if you are runing pyplot inside a GUI and your backend choice
# conflicts, we will automatically try and find a compatible one for
# you if backend_fallback is True
#backend_fallback: True
#interactive : False
#toolbar : toolbar2 # None | classic | toolbar2
#timezone : UTC # a pytz timezone string, eg US/Central or
Europe/Paris
# Where your matplotlib data lives if you installed to a non-default
# location. This is where the matplotlib fonts, bitmaps, etc reside
#datapath : /home/jdhunter/mpldata
### LINES
# See
http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.lines
for more
# information on line properties.
#lines.linewidth : 1.0 # line width in points
#lines.linestyle : - # solid line
#lines.color : blue

### PATCHES
# Patches are graphical objects that fill 2D space, like polygons or
# circles. See
#
http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.patches

### FONT
#
# font properties used by text.Text. See
# http://matplotlib.sourceforge.net/api/font_manager_api.html for more
# information on font properties. The 6 font properties used for font
# matching are given below with their default values.
#
# The font.family property has five values: 'serif' (e.g. Times),
# 'sans-serif' (e.g. Helvetica), 'cursive' (e.g. Zapf-Chancery),
# 'fantasy' (e.g. Western), and 'monospace' (e.g. Courier). Each of
# these font families has a default list of font names in decreasing
# order of priority associated with them.
#
# The font.style property has three values: normal (or roman), italic
# or oblique. The oblique style will be used for italic, if it is not
# present.
#
# The font.variant property has two values: normal or small-caps. For
# TrueType fonts, which are scalable fonts, small-caps is equivalent
# to using a font size of 'smaller', or about 83% of the current font
# size.
#
# The font.weight property has effectively 13 values: normal, bold,
# bolder, lighter, 100, 200, 300, ..., 900. Normal is the same as
# 400, and bold is 700. bolder and lighter are relative values with
# respect to the current weight.
#
# The font.stretch property has 11 values: ultra-condensed,
# extra-condensed, condensed, semi-condensed, normal, semi-expanded,
# expanded, extra-expanded, ultra-expanded, wider, and narrower. This
# property is not currently implemented.
#
# The font.size property is the default font size for text, given in pts.
# 12pt is the standard value.
#
#font.family : sans-serif
#font.style : normal
#font.variant : normal
#font.weight : medium
#font.stretch : normal
# note that font.size controls default text sizes. To configure
# special text sizes tick labels, axes, labels, title, etc, see the rc
# settings for axes and ticks. Special text sizes can be defined
# relative to font.size, using the following values: xx-small, x-small,
# small, medium, large, x-large, xx-large, larger, or smaller
#font.size : 12.0
font.serif : Bitstream Vera Serif, New Century Schoolbook, Century
Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus Roman No9 L, Times New
Roman, Times, Palatino, Charter, serif
font.sans-serif : Adobe Song Std, Bitstream Vera Sans, Lucida Grande,
Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
