Details on demand
Jump to navigation Jump to search
The details on demand–technique allows interactively selecting parts of data to be visualized more detailed while providing an overview of the whole informational concept.
We distinguish between the refinement methods detail on demand, where the user requests greater detail, and progressive refinement, where the system transmits and displays more detail automatically. Both methods can be combined, too. In order to save bandwidth, it is essential that only differential data are transmitted.
The details-on-demand technique provides additional information on a point-by-point basis, without requiring a change of view. This can be useful for relating the detailed information to the rest of the data set or for quickly solving particular tasks, such as identifying a specific data element amongst many, or relating attributes of two or more data points. Providing these details by a simple action, such as a mouse-over or selection (th "on-demand" feature) allows this information to be revealed without changing the representational context in which the data artifact is situated.
