A system for graphically displaying an item (having a plurality of elements) on a display device as the item appears at a preselected time in a timeline first determines which of the plurality of elements are later in the timeline than the preselected time. Once this is determined, first and second sets of elements are defined, in which the elements in the first set each have a respective associated time that is no later than the preselected time. The second set of elements, however, includes each of the elements not in the first set of elements. The number of elements in each of the first set and the second set can range from no elements to many elements. The elements in the first set are drawn on the display device in a first format, and the elements in the second set are drawn on the display device in a second format. The second format, however, graphically indicates that the elements in the second set have respective times that each are later than the preselected time. As such, the first format and second format preferably are different.
