Controlling graph expansion
You can use the Expansion tab to control how nodes react when you click Expand.
Force recount: Refreshes the count on nodes after you make changes.
Dashboard Filters: Applies the filters from a specific dashboard to the graph. This restricts the nodes that are produced by an expansion to those that are present in the selected dashboard.
Relations - simple: Restricts the nodes that are produced by an expansion to the relations that you specify.
Relations - aggregated: These are relations that aggregate nodes in their edges (edges are lines that connect any two nodes on the graph).
