错误，将绘制曲线的Pyplot添加到QgraphicsView

Question

我对此很陌生，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。 我试图遵循该网页的答案，但我似乎犯了一个错误。 将 Matplotlib 绘图作为 QGraphicsItem/放入 QGraphicsView< /a>

错误

Traceback (most recent call last):

问题解决了。

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)
