ABSTRACT:
A method and system for indicating boundaries of data subsets that are displayed in a display window in a data processing system. Data having data subsets are displayed within a display window with a selected data subset being visible within the window. The selected data subset has an upper and lower boundary. A marker is displayed in association with the display window in response to a selected data subset within the plurality of data subsets being displayed within the display window. The marker has two terminuses, an upper terminus and a lower terminus. The location of the upper terminus indicates an upper boundary of the selected data subset and the location of the lower terminus indicates the lower boundary of the selected data subset. An absence of one of the two terminuses intuitively indicates, to a user, a presence of additional undisplayed data within the selected data set that is not displayed within the display window. An absence of the upper terminus indicates that the upper boundary of the selected data subset is not visible, and an absence of the lower terminus indicates that the lower boundary of the selected data subset is not visible. The slope of the sides of the marker provide an indication of how far away the absent terminus is from the visible portion of the marker.
