How to embed this matplotlib code into tkinter canvas?

The matpl开发者_StackOverflowotlib code is in http://matplotlib.sourceforge.net/examples/animation/strip_chart_demo.html

I want to embed this code in my tkinter GUI,what should I do ? As it say"""This example uses gtk but does not depend on it intimately. It just uses the idle handler to trigger events. You can plug this into a different GUI that supports animation (GTKAgg, TkAgg, WXAgg) and use your toolkits idle/timer functions."""

What's the idle/timer function in TkAgg?
