The Other Views Tab is essentially a workspace that displays the details associated with the links available in any of the gauges.
For instance, when you click a data link on one of the gauge tabs, the details for the associated data is copied over to the Other Views tab where you can study it in an isolated view. Any data that you place on the Other Views tab remains there until you click another link. This allows you to go back to any of the other gauges to compare or cross-reference the details.
