Use custom properties to show historical summary data

You can add a custom property to reference historical data collected over a specified period during runtime. The Historian can transform this data to create a set of analog or state statistics that can be shown by Industrial graphic animation during runtime.

For example, consider an example of a temperature meter graphic that shows an optimal temperature range and you would like to know what the average temperature has been over the last 15 minutes. You can add a Value Display animation that shows the average temperature derived from analog temperature data saved in the Historian and referenced by a custom property.
