Dear Gökhan,thanks a lot for your reply and help! I could solve some of my problems, others remain elusive.

Probably you need a unicode font-set that contain all the characters for those alphabets. You can look at this example to see a simple unicode demonstration example.
Yes, I have done that, for example: ylab = plt.ylabel(u'输入 2')
Make sure you are using the right font in your matplotlib.
Well, here I get stuck. I checked the fontList.cache, and all the relevant CJK fonts are listed in there. I then added some CJK font names to my /etc/matplotlibrc: (I am using Ubuntu 9.10)
#font.sans-serif : SimHei, Adobe Song Std, Bitstream Vera Sans, ... #font.cursive : Apple Chancery, ... #font.fantasy : Comic Sans MS, ... #font.monospace : Adobe Fangsong Std, Bitstream Vera Sans Mono, ... In addition, I also defined rcParams['font.sans-serif'] = ['SimHei'] in my Python code (attached). All to no avail. I am at a loss. I would greatly appreciate some help here!
You have to adjust your label to get it seen. You may try with:
xlab = plt.xlabel("my x-axes label")
xlab.set_position((0.2, 0.1))
This did not yield any results. With the above code, xlab.set_position((0.2, 0.1)), I change the position of the xlabel. But the problem is that my graph is cut before the xlabel has a chance to appear (see dea.png). Basically the graph ends right after the x-axis. What I thus need is more whitespace under my x-axis. But how?
Two ways I can think of are: annotate and text functions of pyplot api. http://matplotlib.sourceforge.net/api/pyplot_api.html
This worked fine! What I did was to define text( 1, 4.2, u'A') etc. Thanks for your ideas and insights! David
