Grouping Displays is used to link Time Scales among Displays. All Time Scales of a group contain the same zoom factor, but with different periods. This allows comparing different periods through a search, such as comparing a certain month to the previous month.

To create a group of Displays, click the icon on the title bar of the Displays. To remove a Display from a group, click the icon on the title bar of the Display.

When grouped, all Displays share the same reproduction mode. Click the icon to play and the icon to pause reproduction. The Search, Zoom, and Select modes are executed in all Displays of a group, according to the relation among periods.
