About limit trend displays
Limit trend displays are similar to standard trend displays. However, they also include
information about relevant limits that have been sourced by integrating Experion with Limit
Repository.
When configuring a Limit trend, you can specify the required history interval to be viewed.
(History intervals are the periods between snapshots and the periods over which averages are
calculated. These periods are then used for collecting history).
The number of trends available in your system depends on the server database sizing.
