<p>A system for displaying time-based events on a time line is described. A first timeline unit (1) displays a first timeline showing a first plurality of events within a first time segment (3) bounded by a first begin time and a first end time. A second timeline unit (2) displays a second timeline showing a second plurality of events within a second time segment (4) bounded by a second begin time and a second end time, wherein the first timeline and the second timeline are displayed in the same scale. An interaction unit (5) enables a user to indicate a change to the displayed time segments (3, 4). A time segment updater (6) determines an updated first time segment (3) and an updated second time segment (4) based on the indicated change, keeping the scale of the first timeline equal to the scale of the second timeline, and keeping an offset between the first time segment (3) and the second time segment (4) constant. The timeline units (1, 2) are arranged for updating their respective displays according to the updated time segments (3, 4).</p> |
