Matplotlib 是一个 Python 的 2D绘图库，它以各种硬拷贝格式和跨平台的交互式环境生成出版质量级别的图形。

有时候，我们想把matplotlib嵌入到wxpython，这样再利用pyinstaller打包便可形成一个脱离python编译器独立的画图工具。

下面是将matplotlib嵌入到wxpython的代码。

有点难度的地方在于：一是要把Matplotlib图像放到界面上去；二是定义绘图函数，也用过别的方法，都不完美，现在这种方法可以实现需求。其中每次绘图使用不同的颜色可以有两种方法，一种是使用rgb数值，每次改变数值，另一种是定义颜色列表，每次随机选取。
运行后的效果如下：


现在可以调节Kp，Ki，Kd的值来观察各参数对PID控制的影响。
