ABSTRACT:
A data processing system provides a graphic user interface on which is displayed a scroll bar including a current value position and showing sequential numerical values adjacent to the current value in the current value position. Selection graphics provide for user selection of values, and to expand or reduce value resolution. A graphic metaphor for a spin button provides for incrementing or decrementing the range of values within the display field of the scroll bar.
