我有一個(gè)腳本，將一個(gè)簡單的情節(jié)嵌入到 Tkinter gui 中。有一個(gè)用于繪圖的按鈕，當(dāng)按下它時(shí)，它似乎什么也沒做，但如果窗口稍微調(diào)整大小，繪圖就會(huì)彈出。gui 窗口足夠大以包含情節(jié)，我在這里做錯(cuò)了什么？代碼print('\n'*3)import tkinter as tkimport matplotlib.pyplot as plt  from matplotlib.backends.backend_tkagg import FigureCanvasTkAggfrom matplotlib.figure import Figure#MAKE ROOT WINDOWroot = tk.Tk()root.title("Tab Widget")#root.geometry("600x450")#MAKE A FIGURE OBJECTmy_figure = Figure(figsize = (4, 4), dpi = 100) #MAKE A FRAME WIDGETframe1 = tk.Frame(root, bd=2, relief=tk.GROOVE)frame1.pack(side=tk.LEFT, anchor=tk.N, fill=tk.BOTH, expand=True)frame2 = tk.Frame(root, bd=2, relief=tk.GROOVE)frame2.pack(side=tk.RIGHT)#MAKE A CANVAS OBJECTmy_canvas = FigureCanvasTkAgg(my_figure, master = frame1) # creating the Tkinter canvas containing the Matplotlib figure  # TURN THE CANVAS OBJECT INTO A CANVAS WIDGETmy_canvas.get_tk_widget().pack() # placing the canvas on the Tkinter windowmy_canvas.draw()def plotData():    plot1 = my_figure.add_subplot(111) # adding the subplot     x = [1,2,3,4,5]    y = [11, 3, 6, 9,12]    plot1.plot(x, y, marker='o', c='b')# MAKE BUTTON TO PLOT GRAPHbutton1 = tk.Button(frame2, text = "Plot", command = plotData, relief = tk.GROOVE, padx =20, pady =20 )button1.pack(side="right")root.mainloop()期望的結(jié)果無需調(diào)整大小即可查看繪圖的 GUI 窗口。
