Your animation is now ready to play in both the graph and the display.

Click Options on the Animation Controls dialog box to expand the Play options part of the dialog box. Ensure that Restore state after playing is unchecked so the last frame will be retained after playing the animation. Also check the number of frames that will display is 21, and the frame duration is 0.1.

Click the Play button. Examine the recorded population changes over time in the display and in the graph.
