感谢 yungyuc，不过我之前都使用 tarball 安装，大概是因为这样，整个相依性都挂了，
搞到不清楚到底是谁有问题，後来决定整个重来，除了 networkx、psyco 之外，
全都使用系统套件安装，总共安装了 numpy、matplotlib、tkinter、scipy 及其套件，
像是 pygtk、pyobject、pycairo、gtk、tk、tcl 之类的全都顺便安装，
因为不确定可能会少什麽的情况下，只好全部都安装，以确保不会少东西，
不过还是出现了以下错误：

查了资料後发现，问题还是在 backend，安装好的 matplotlibrc 初始设定是 GTKAgg，
於是我就改成 TkAgg，

self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable
依然有问题，後来看到里面支援比较多的是 Cairo 和 GDK，於是就改成 Cairo 来试试，
想不到就可以正确的把图 show() 出来了。
