tkinter 显示matplotlib的图

可以使用Tkinter和Matplotlib库来显示Matplotlib的图形。具体步骤如下：

1. 导入Tkinter和Matplotlib库

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

2. 创建Tkinter窗口和Matplotlib图形

root = tk.Tk()
root.title("Matplotlib图形显示")

fig = Figure(figsize=(5, 4), dpi=100)
ax = fig.add_subplot(111)
ax.plot([1, 2, 3, 4, 5], [10, 5, 20, 15, 25])

3. 将Matplotlib图形嵌入到Tkinter窗口中

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

4. 运行Tkinter窗口

tk.mainloop()

完整代码如下：

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

root = tk.Tk()
root.title("Matplotlib图形显示")

fig = Figure(figsize=(5, 4), dpi=100)
ax = fig.add_subplot(111)
ax.plot([1, 2, 3, 4, 5], [10, 5, 20, 15, 25])

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

tk.mainloop()
