基于python实时监控cpu的小工具

虽然写的很不完善，但是当练手吧，对于实时监控cpu还是有点用处的，虽然android studio已经提供了一样的功能，但是能够记录并生成成本地csv文件还是比as多一个功能的。

结果图：

直接放源码：

if __name__ == '__main__':
    app = wx.App()
    MyFrame().Show()
    app.MainLoop()

原理：
界面用wx做的，图形用pychartdir做的，命令用的是top命令，每次截取到的数据都生成一张临时图片，然后刷新到屏幕上，看起来就是实时数据监控的效果了，基本上BUG一大堆，也懒得改了。
