Figure 7.   History Groupings component comes as part of the HistoryService

The History Groupings component, located under the HistoryService, specifies which History properties to filter on for organizing a station’s History space. These alternative navigation displays are based strictly on the History properties that you select and are a departure from the device- or driver-centered navigation model that builds a Nav tree based upon networks, devices, and points.

With History properties, you can use one or more HistoryGroup components to set up Central Region, functional, or any other desired organization of your History space. You can create multiple navigation schemes and use them, as needed, or use the default history navigation structure, which always remains visible. History grouping allows you to simultaneously display histories in multiple Nav paths, as shown below.
