Parameter selection

The historic data dialog will only display the first 15 selected parameters by default. Use the Parameter selection panel accessible via the arrow on the right to refine your selection and change how the data should be displayed, including any aggregate calculations to be applied.



Auto will use the default chart options for each parameter (as configured in parameter properties).

Custom allows you to specify custom display settings for each parameter. These settings are shared between table and exports for convenience.

Display type

Value displays the parameter values.

State displays the state name associated with each value.

Aggregates provide a method to resample raw data over a specified period. See the list of available aggregates for full details. Select RAW to display the original raw data with no aggregation applied (Interval and Base time options will be hidden).
Specify the data range that is included for each calculated value. Example 30M will calculate a value for each 30 minute window of data.
Base time
Base time is used to determine the start of the aggregate calculations. Example D+9H will start the calculations at 9am (start of current day + 9 hours). See working with relative time for full details.


Please be aware that displaying RAW data for a large time range may be time consuming to retrieve and process.
