You'll now add the State Population layer as another attached object to the time layer track you created earlier. Doing so will enable the data in the graph (the State Population layer) to animate at the same time as the data in the display (the County Population layer). Another way to achieve this result is to create another time layer track and attach the State Population layer to it.

To do so, click Animation and click Animation Manager. Click the Tracks tab and click the track to select it. Click Properties. Click the General tab, click State Population from the Available objects list, then click Attach.

Click the Time Track Properties tab and click State Population. Click the Start Time Field drop-down arrow and click Start_Date. Click OK. Click Close on the Animation Manager dialog box.

Click File on the Main Menu and click Save.
