python - 如何在主应用程序 Pyqt 中插入产生其他线程的 matplotlib 图 ..？

Question

我想使用 Pyqt5 制作监控应用程序并使用线程检查状态。

当应用程序状态更改时制作情节。但情节是由应用程序制作的。我希望那是在 pyqt 应用程序中制作情节。

在查看我的代码下。

class WindowClass(QDialog):

    def __init__(self) :

        QDialog.__init__(self, None)

    def test_6(self):

# thread is check for status changing

        if is_thread_on == False:

            schedule_thread = threading.Thread( target = self.scheduled )
            schedule_thread.daemon = True
            schedule_thread.start()


    def scheduled(self):

        schedule.clear()
        schedule.every(15).seconds.do( self.process_check )

    def new_print_plot(self):

        for i in range( 0 , 10 ) ):

            fig = plt.Figure()
            ax = fig.add_subplot(111)
            ax.scatter( x = x_length , y = data )

            canvas = FigureCanvas( fig )
            canvas.draw()

            self.horizontalLayout.addWidget( canvas )
            canvas.show()            

当你看到张贴的图片时。你可以很容易地理解我的目的。

请帮我。
