看 phonopy 的文档：

如果你想把数据放在 origin 等软件里面画图，直接执行
bandplot –gnuplot band.yaml > band.dat
就可以了。
提示：其中 band.dat 的第一行是 q 点的位置。

Band structure is plotted reading phonopy output in band.yaml format. -o option with a file name is used to save the plot into a file in PDF format. A few more options are prepared and shown by -h option. If you specify more than two yaml files, they are plotted together.
To obtain a simple text format data:bandplot band.yaml
bandplot --gnuplot band.yaml
bandplot –gnuplot band.yaml > band.dat
就可以了。
提示：其中 band.dat 的第一行是 q 点的位置。
