Abstract
An elevator system including at least one elevator car mounted for movement in a building to serve the floors therein, and pushbuttons for entering calls for elevator service. Calls for elevator service initiated by the pushbuttons are visually displayed in a predetermined order on a display in which the display positions for such calls are not specifically related to a specific floor, but which may be used to indicate a call associated with any floor of the building. In a preferred embodiment, the calls are stacked or compressed to provide a predetermined uniform physical spacing between adjacent calls of the predetermined order. The predetermined order and predetermined spacing are maintained as new calls are entered on the display, and answered calls are deleted therefrom.
