# coding=utf-8 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( "服务器之家测试 - 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() |
二. 运行结果:
希望本文所述对大家Python程序设计有所帮助。
