SimpleGUI在畫布中顯示mpf.plot

下面的代碼會將 Matplotlib 工具列嵌入到應用程式中，并將繪圖嵌入到特定的畫布中，但我想嵌入我的 mpf.plot 而不是我的 plt.plot。該代碼運行良好，但不會產生預期的結果，請提供任何建議

uj5u.com熱心網友回復：

添加選項returnfig=True以mpf.plot使其回傳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)
