Attach the graph data to the time layer track

There are 5 steps to add an animated graph to an existing animation in ArcMap.
1) Choose the data to be graphed.
2) Create the graph.
3) Adjust the graph properties for an animation.
4) Attach the data to the Time Layer Track.
5) Play the animated graph.

In this segment you'll attach the graph data to the Time Layer Track

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 attach a layer to a time layer track, open the Animation Manager. Click Animation and click Animation Manager. Click the Tracks tab and click the track to select it, then click Properties.

Click the General tab, click State Population from the Available objects list, then click Attach.

Now that the data is attached to the time layer track, you'll tell the animation manager what field contains time values in the State Population layer. Click the Time Track Properties tab and click State Population. Click the Start Time Field drop-down arrow and click Start_Date, then click OK.

Close the Animation Manager dialog box.

The State Population layer data and the graph derived from it are now attached to the time layer track, so the counties on the map and the state population graph will be synchronized for any given time slice, or when you play the animation.
