Using Operative Sets

An operative set is a set of events defined by the user to be highlighted in the range navigator. You can select certain components of a recording for which events should be highlighted. For example, you can add certain events to the operative set to see when during the recording they occurred, and then adjust the range navigator to just that time period.

The following figure shows a portion of the range navigator with the events from the operative set highlighted. The range navigator is a bar graph where the x-axis is the time (recording start time is set to 3:30:00 AM), and the y-axis is the number of events that happened at a certain point in time. The legend above the range navigator shows two items: orange denotes all events, and blue denotes events from the operative set. In the graph itself, blue bars are overlaid on top of the orange bars, giving you an idea of how the number of events from the operative set compares to the total number of events.

Example of how events from an operative set are highlighted in the range navigator.

You can add data to the operative set using rows in most tables and events in the Event Graph (the Graph tab in the Events tab group). The operative set is preserved when switching between tabs. This means that you can add events to the operative set on one tab, and view the operative set in the range navigator in another tab. However, make sure that the tab you are viewing contains events that you want to see in the operative set.

To configure the operative set, right-click the selected rows in a table or the events in the Event Graph, select Operative Set, and then select one of the following options:
