One can display a patient's medical history on a (color-coded), bar-configured chronological timeline. The patient timeline display includes event markers that are located adjacent to specific time increments along the patient timeline when the patient had certain procedures performed. Namely, each procedure is represented by an event marker referenced to its time of performance along the timeline. From the basic bar-configured timeline which contains a pop-up bubble, the physician can see at a glance every major hospital encounter a particular patient has had over the duration of the timeline, e.g., the last 12-months.
