我是matplotlib的新用户,我的平台是Ubuntu 10.04 Python 2.6.5

这是我的代码

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt 
plt.plot([1,2,3])

错误是:

/usr/local/lib/python2.6/dist-packages/matplotlib/backends/__init__.py:41: UserWarning: 
Your currently selected backend, 'agg' does not support show().
Please select a GUI backend in your matplotlibrc file ('/usr/local/lib/python2.6/dist-packages/matplotlib/mpl-data/matplotlibrc')
or with matplotlib.use()
  (backend, matplotlib.matplotlib_fname()))

• 我安装了Anti-Grain Geometry库,apt-get install libagg但它不起作用.
• 我尝试使用后端的其他参数,如'GTK'和'TkAgg'.
• 我安装了python-gtk2-dev包,但仍然出现错误.
• 谁能告诉我一个可执行的后端参数及其依赖库？

这是错误:

>>> matplotlib.use('GTK')
>>> import matplotlib.pyplot as plt
