When embedding Matplotlib in a GUI, you must use the Matplotlib API directly rather than the pylab/pyplot procedural interface, so take a look at the examples/api directory for some example code working with the API. 在本教程中，我们研究了如何在PyQt6应用程序中嵌入Matplotlib绘图。 From my perspective, this task is best accomplished by getting matplotlib to render into an uncompressed image format and then getting PyQt6 to draw that into an area of the user interface. 将 Matplotlib 的图形（Figure）对象嵌入到一个 PyQt 应用程序中，以便在 GUI 窗口中显示图表。最后，你可以将图表添加到自己的布局中。 On my Mac, I had to put the lines 'import matplotlib' and 'matplotlib. This scheme was dropped when support for Qt6 was added. backend_qt4agg import FigureCanvasQTAgg as FigureCanvas.
