在tkinter中使用matplotlib

import sys

import tkinter as Tk

import matplotlib

from numpy import arange, sin, pi

from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg

from matplotlib.backend_bases import key_press_handler

from matplotlib.figure import Figure

matplotlib.use('TkAgg')

root = Tk.Tk()

root.title("matplotlib in TK")

# 设置图形尺寸与质量

f = Figure(figsize=(5, 4), dpi=100)

a = f.add_subplot(111)

t = arange(0.0, 3, 0.01)

s = sin(2 * pi * t)

# 绘制图形

a.plot(t, s)

# 把绘制的图形显示到tkinter窗口上

canvas = FigureCanvasTkAgg(f, master=root)

canvas.show()

canvas.get_tk_widget().pack(side=Tk.TOP, fill=Tk.BOTH, expand=1)

# 把matplotlib绘制图形的导航工具栏显示到tkinter窗口上

toolbar = NavigationToolbar2TkAgg(canvas, root)

toolbar.update()

canvas._tkcanvas.pack(side=Tk.TOP, fill=Tk.BOTH, expand=1)

# 定义并绑定键盘事件处理函数

def on_key_event(event):

    print('you pressed %s' % event.key)

    key_press_handler(event, canvas, toolbar)

    canvas.mpl_connect('key_press_event', on_key_event)

# 按钮单击事件处理函数

def _quit():

    # 结束事件主循环，并销毁应用程序窗口

    root.quit()

    root.destroy()

    button = Tk.Button(master=root, text='Quit', command=_quit)

    button.pack(side=Tk.BOTTOM)

Tk.mainloop()
