pyplot交互地画多个plot

下面的代码，可以无阻碍地show 5个figure，相当于开启了ipython的interactive 模式

具体参见stackoverflow: in matplotlib, is there a way to pop up a figure asynchronously?

 1 #!/usr/bin/python
 2 import pylab as plb
 3 import matplotlib.pyplot as plt
 4 def show_figure():

 5 　　fig1=plt.figure(1)
 6 　　ax = fig1.add_subplot(1,1,1)
 8 　　ax.plot([1,2,3],[4,5,6],'ro-')
11 　　plt.ion()     # turns on interactive mode
12 　　plt.show()    # now this should be non-blocking
13 
　　for i in range(5):
　　　　show_figure()

14 print "doing something else now"
15 raw_input('Press Enter to continue...')
