python – 在while循环中生成绘图后在KeyboardInterrupt上退出

我正在使用matplotlib实时监控实验,以在while循环中生成绘图.理想情况下,循环应该退出像KeyboardInterrupt这样的东西.这在Ubuntu测试中运行良好.在 Windows 7中,使用ipython,它会以“终止批处理作业(是/否)？”退出.然后关闭翻译.我想避免这种行为,并在KeyboardInterrupt之后保持解释器打开.这是一个测试脚本.

[编辑2]：如果ipython作为ipython –pylab加载,此脚本在Windows中可以正常工作.

import time
import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
line,= ax.plot([0],[0],'b-o')

window = 50
plot_data = np.zeros((window,2))

i = 0
start = time.time()
while True:
    try:
        data = [time.time() - start,np.random.rand()]
        print ' '.join('{:.2f}'.format(x) for x in data)
        if i < window:
            plot_data[i,:] = data
            line.set_data(plot_data[0:i+1,0],plot_data[0:i+1,1])
        else:
            plot_data[0:window-1] = plot_data[1:window]
            plot_data[window-1] = data
            line.set_data(plot_data[:,plot_data[:,1])
        ax.relim()
        ax.autoscale_view(True,True,True)
        fig.canvas.draw()
        plt.pause(0.1)
        i += 1
    except KeyboardInterrupt:
            print "Program ended by user.n"
            break 
print 'Success!'

[编辑1]：我应该更清楚为什么我用matplotlib标记这个.以下示例脚本在任一操作系统中都不会出现问题.

i = 0 
start = time.time()
while True:
    try:
        data = [time.time() - start,np.random.rand()]
        print ' '.join('{:.2f}'.format(x) for x in data)
        time.sleep(0.1)
    except KeyboardInterrupt:
        print "Proram ended by user. n"
        break
print 'Success!'

昨天安装了所有软件包,作为Enthought的全新安装的一部分.

print 'press 'q' to end run'
time.sleep(1.0)

fig = plt.figure()
ax = fig.add_subplot(111)
line,'b-o')

window = 150
plot_data = np.zeros((window,2))

i = 0
start = time.time()
while True:
    data = [time.time() - start,np.random.rand()]
    print ' '.join('{:.2f}'.format(x) for x in data)
    if i < window:
        plot_data[i,:] = data
        line.set_data(plot_data[0:i+1,1])
    else:
        plot_data[0:window-1] = plot_data[1:window]
        plot_data[window-1] = data
        line.set_data(plot_data[:,1])
    ax.relim()
    ax.autoscale_view(True,True)
    fig.canvas.draw()
    plt.pause(delay)
    i += 1
    if msvcrt.kbhit():
        if ord(msvcrt.getch()) == 113:
            print "Program ended by user.n"
            break 
print 'Success!'
