将matplotlib嵌入tkinter canvas将打开两个窗口

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

# 创建tkinter窗口
root = tk.Tk()

# 创建matplotlib的Figure对象
fig = Figure()

# 在Figure对象上创建子图
ax = fig.add_subplot(111)
ax.plot([1, 2, 3, 4, 5], [1, 2, 3, 4, 5])

# 创建FigureCanvasTkAgg对象，将Figure对象嵌入到tkinter的canvas中
canvas = FigureCanvasTkAgg(fig, master=root)
canvas.draw()

# 在tkinter窗口中放置canvas
canvas.get_tk_widget().pack()

# 运行tkinter主循环
root.mainloop()
