替换Tkinter中修复的按钮上的FigureCanvasTkAgg内容

import tkinter as tk
from matplotlib.figure import Figure
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

# 创建Tkinter窗口
window = tk.Tk()

# 创建一个Figure对象
figure = Figure(figsize=(5, 4), dpi=100)
subplot = figure.add_subplot(111)

# 绘制原始图形内容
subplot.plot([1, 2, 3, 4, 5], [1, 2, 3, 4, 5])

# 创建一个FigureCanvasTkAgg对象，并将其嵌入到Tkinter窗口中
canvas = FigureCanvasTkAgg(figure, master=window)
canvas.draw()
canvas.get_tk_widget().pack()

# 创建一个按钮，用于替换FigureCanvasTkAgg内容
def replace_content():
    # 创建一个新的Figure对象
    new_figure = Figure(figsize=(5, 4), dpi=100)
    new_subplot = new_figure.add_subplot(111)

    # 绘制新的图形内容
    new_subplot.plot([1, 2, 3], [1, 4, 9])

    # 创建一个新的FigureCanvasTkAgg对象，并将其替换原有按钮上的FigureCanvasTkAgg对象
    new_canvas = FigureCanvasTkAgg(new_figure, master=window)
    new_canvas.draw()
    new_canvas.get_tk_widget().pack()

# 创建一个按钮，点击按钮时替换FigureCanvasTkAgg内容
replace_button = tk.Button(window, text="替换内容", command=replace_content)
replace_button.pack()

# 运行Tkinter窗口的主循环
window.mainloop()
