微波课设基于pyqt5+pyqtgraph的Smith圆图GUI程序设计

学期末要做微波技术课设，老师要求设计一个GUI，和Smith圆图有关

然后选用python里面的pyqt5设计出一个交互界面。

思路很简单就是先用qtdesigner搭建框架生成python代码，再把python代码改改就ok

画图本来想用matplotlib，但是这个库交互性没有pyqtgraph强，所以画图用了pyqtgraph。

pyqtgraph库里面的十字光标参考了https://zmister.com/archives/793.html

但是链接里面文章不能拿来直接跑：（这句话有问题）

if self.k_plt.sceneBoundingRect().contains(pos):

绘制Smith圆图也很简单，两个圆的方程用极坐标就ok了（还是有一些bug）

不多废话直接上代码
