The Trails feature in the Motion Chart lets you connect the dots to understand how a dimension (or bubble) changes from day to day. This feature is especially convenient if you have multiple dimensions, but only want to track the progression of one.
To enable trails:
- Select the dimensions that you want to track by clicking the corresponding bubbles.
- Select the Trails checkbox below the list of dimensions.
- Click the Play control at the bottom of your chart.
You see a line trace the progress of each dimension that you selected.
