Change the Historical time interval

The Current Data Summary window displays data for the four most recent operating points. In a Historical Operating Point Table window, the number of points displayed depends on the selected time range.

The default start time is the most recent top-of-hour for long-term mode, and the most recent top-of-minute for short-term mode. The default end time is also based on the mode selected. In short-term mode, the default end time is one hour. In long-term mode, the default end time is one day.

Note: The expected number of points may not appear in the Operating Point Table window if the performance curve set has been recently reassigned, or if you try to view data from a time period in which the current curve set was not in use. For more information, refer to Open the Compressor Plot window.
