As an administrator you can help prevent performance degradation by setting limits on graph display. The add-on allows you to limit the number of records users can select to display in a graph, and the number of nodes they can expand using the following properties:
Record selection limit: Determines the maximum number of records users can select when generating a graph.
Expanded nodes limit: Specifies the total number of nodes that users can expand in a single graph. If users attempt to expand a number of nodes over this threshold, a pop-up displays that allows them to choose which nodes to display.
To set limits on node display:
Navigate to Administration > User interface > TIBCO EBX® Data Model and Data Visualization Add-on > Global properties and options > Global properties.
Specify the Record selection limit and Expanded nodes limit for the:
Display data using configuration service (note that the Expanded nodes limit property also applies to standard Org charts, but not those in Step by step mode)
