QT 显示 Matplot 的绘画图，位置怎么确定,可以自己构建 ,QT 组件，然后随意拖拽，就可以在自己的UI 界面中随意显示
需要做类的提升
参考这篇博文
https://blog.csdn.net/g11023225/article/details/119274622
绘图类的模块应用，感谢 github丰富的代码

python 复制代码

from PyQt5.QtWidgets import*
from matplotlib.backends.backend_qt5agg import FigureCanvas
from matplotlib.figure import Figure

# TODO: MORE SUB PLOT NEED ADD
class matplot(QWidget):
    def __init__(self, parent = None):
        QWidget.__init__(self, parent)        
        self.canvas = FigureCanvas(Figure())
        vertical_layout = QVBoxLayout()
        vertical_layout.addWidget(self.canvas)        
        self.canvas.axes = self.canvas.figure.add_subplot(111)
        self.setLayout(vertical_layout)

可以在 desigin 中进行拖拽，复制模块儿
