Synchronoptic view
A synchronoptic view is a graphic display of a number of entities as they proceed through time. A synchronoptic view can be used for many purposes but is best suited to the visual display of history. A number of related timelines can be drawn on a single chart showing which events and lives are contemporary and which are unconnected.
A synchronoptic view has important educational advantages. Visible information is much more easily learned, than when it is presented only in pure text form. History is an ideal subject for a synchronoptic view. Multiple timelines are able to show how events interacted. Multiple lifelines can show which people were contemporaries.
(See example)
A combination of maps is also synchronoptic when it displays successive moments in time.
Etymology
The concept in question is made visual — hence optic.
The elements are displayed synchronously: i.e. which events in one area happened at the same time as events in another seemingly unrelated area.
Thus synchron-optic.
