python - 传递要在 tkinter 选项卡中绘制的图形

Question

我正在尝试有一个在 tkinter 中绘制图形的按钮。要绘制的图形是 matplotlib.image.AxesImage

当前代码只是绘制了一个空白图，我不知道为什么

谁能帮忙？

def plot_gui():
    fig = plt.Figure(figsize=(6,5), dpi=100)
    ax = fig.add_subplot(111)
    chart_type = FigureCanvasTkAgg(fig, tab2)
    ax = fo2.plotgas()

    canvas = FigureCanvasTkAgg(ax,master=tab2)
    #canvas.show()
    canvas.get_tk_widget().grid(row=9,column=9)
    #canvas.draw()   

fo2.plotgas() 只是产生我试图显示的数字

编辑这里是最小的可运行示例

root.mainloop()

错误是

AttributeError: 'AxesImage' object has no attribute 'set_canvas'
