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“防颗粒几何”库,
apt-get install libagg
但是它不起作用。 - 我试图使用后端的其他参数,例如“ GTK”和“ TkAgg”。
- 我安装了
python-gtk2-dev
软件包,但错误仍在下面。 - 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
