将绘制曲线的 pyplot 添加到 QGraphicsView 时出错

Question

我是新手，想知道在使用 Pyuic 转换的 py 文件时尝试添加绘图时出了什么问题。我试着按照这个网页的答案，但我似乎犯了一个错误。 Put a Matplotlib plot as a QGraphicsItem/into a QGraphicsView

错误

Traceback (most recent call last):

    proxy_widget=self.scene.addWidget(canvas)
TypeError: addWidget(self, QWidget, flags: Union[Qt.WindowFlags, Qt.WindowType] = Qt.WindowFlags()): argument 1 has unexpected type 'FigureCanvasTemplate'

问题已解决

我导入 from matplotlib.backends.backend_template import FigureCanvas，现在导入 from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas。

self.Plotting.setScene(proxy_widget) 到 self.Plotting.setScene(self.scene)
