可以在Python语言中使用组合框来更改FigureCanvas吗？

import tkinter as tk
from tkinter import ttk
import matplotlib.pyplot as plt
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

def update_plot(event):
    selected_plot = combobox.get()
    ax.clear()
    if selected_plot == "sin":
        x = [i for i in range(100)]
        y = [np.sin(i/10) for i in x]
        ax.plot(x, y)
    elif selected_plot == "cos":
        x = [i for i in range(100)]
        y = [np.cos(i/10) for i in x]
        ax.plot(x, y)
    canvas.draw()

root = tk.Tk()
root.title("Plot Selector")

fig, ax = plt.subplots()
canvas = FigureCanvasTkAgg(fig, master=root)
canvas.get_tk_widget().pack(side=tk.TOP, fill=tk.BOTH, expand=1)

combobox = ttk.Combobox(root, values=["sin", "cos"])
combobox.pack()
combobox.bind('<<ComboboxSelected>>', update_plot)

root.mainloop()
