History Display
The history display shows equally time-spaced dots marking past positions of
activated targets being tracked. A new dot is added at preset time intervals until
the preset number is reached. If a target changes its speed, the spacing will be
uneven. If it changes course, its plotted course will not be a straight line.
Below are sample history displays.
