matplotlib plot 绘图函数发生阻塞（block）时的解决方法

Is there a way to detach matplotlib plots so that the computation can continue?

• 在一般编辑器中：

  from matplotlib.pyplot import plot, draw, showplot([1,2,3])draw()print 'continue computation'# at the end call show to ensure window won't close.show()

• 在交互（interactive）模式下（比如 IPython）：

  from matplotlib.pyplot import plot, ion, showion() # enables interactive modeplot([1,2,3]) # result shows immediatelly (implicit draw())print 'continue computation'# at the end call show to ensure window won't close.show()
