Abstract: On a display screen of a computer, temporal data are displayed for use in financial planning. On the display screen, a timeline is displayed in a substantially diagonal orientation relative to a 2-dimensional coordinate system. A first axis of the coordinate system represents a financial amount, and a second axis of the coordinate system represents a time amount. An icon is retrieved and positioned on the display screen to cause the display of at least one or more representations of the icon position in the 2-dimensional coordinate system relative to the timeline.
