Display Area |
The title bar of a Display contains an icon representing the reproduction mode of that Display, which is playing or paused .
When in play mode, the Time Scale moves toward the future, allowing users to follows real-time values. Moving the Time Scale to the past or applying a zoom does not change the Scale's movement direction.
When Displays are grouped, only one of the Displays is in play mode and the other Displays on the group copy that movement. When removing a paused Display from a group, that Display stops its movement. If a Display is added to a moving group, this Display also starts to move.
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.
When right-clicking the area of a Display, the contextual menu of the next figure is displayed, in which users can select the options described on the next table.
