+# Pong
+
+一个使用Matplotlib的小游戏演示。
+
+此示例需要[pipong.py](https://matplotlib.org/_downloads/9a2d2c527d869cd1b03d9560d75d6a71/pipong.py)
+
+```python
+import time
+
+
+import matplotlib.pyplot as plt
+import pipong
+
+
+fig, ax = plt.subplots()
+canvas = ax.figure.canvas
+animation = pipong.Game(ax)
+
+# disable the default key bindings
+if fig.canvas.manager.key_press_handler_id is not None:
+    canvas.mpl_disconnect(fig.canvas.manager.key_press_handler_id)
+
+
+# reset the blitting background on redraw
+def handle_redraw(event):
+    animation.background = None
+
+
+# bootstrap after the first draw
+def start_anim(event):
+    canvas.mpl_disconnect(start_anim.cid)
+
+    def local_draw():
+        if animation.ax._cachedRenderer:
+            animation.draw(None)
+    start_anim.timer.add_callback(local_draw)
+    start_anim.timer.start()
+    canvas.mpl_connect('draw_event', handle_redraw)
+
+
+start_anim.cid = canvas.mpl_connect('draw_event', start_anim)
+start_anim.timer = animation.canvas.new_timer()
+start_anim.timer.interval = 1
+
+tstart = time.time()
+
+plt.show()
+print('FPS: %f' % (animation.cnt/(time.time() - tstart)))
+```
