SimpleGUI 在 canvas 中显示 mpf.plot

Question

下面的代码会将 Matplotlib 工具栏嵌入到应用程序中，并将绘图绘制到特定的 canvas，但我想嵌入我的 mpf.plot 而不是我的 plt.plot。代码运行良好，但不会产生预期的结果，请提出任何建议

Answer 1

将选项 returnfig=True 添加到 mpf.plot 以获得它 return fig, axlist。

        fig, axlist = mpf.plot(
            df,
            type='candle',
            style= colors[10],
            title= colors[10],
            ylabel='Price ($)',
            returnfig=True,
        )

        # ------------------------------- Instead of plt.show()
        draw_figure_w_toolbar(window['fig_cv'].TKCanvas, fig, window['controls_cv'].TKCanvas)
