How to Group Arcs in a Graph
You can group arcs (or path) of the same type or arcs carrying the same field value or the same object value.
The Grouping on values are:
• (by default) "All arcs"
Groups together all of the arcs matching the GraphSet Arc Definition between two node instances.
• "By field"
Groups together all of the arcs carrying the same field value. The grouping field must be displayed either on the graph or in a tooltip.
*If the field is a multivalued attribute, its picture is shown in the tooltip.
*Restricted to one object type.
• (path-based arc only) "By object"
Groups together all of the arcs carrying the same objects.
To group arcs of the same type:
1. Access the Report Graph Arc properties.
*Access the Report Graph View and expand its Report Graph Layer concerned, see Accessing the Report Templates and their Constituents.
2. In the Properties window , display its Characteristics page.
3. In the Grouping specifications section, in the Grouping on field, use the drop-down list to select the grouping criteria.
4. If you selected a grouping:
• By field: in the Object or Field field, use the drop-down list to select one of the available fields of the nodes.
• By object: in the Object or Field field, use the drop-down list to select the object.
*You can set a display on details of your arc grouping
Setting a display on details of an arc grouping 
From an arc grouping tooltip, you can display its detailed list of objects, either:
• (path-based arc only) the list of objects of one of its intermediate nodes (Nodes), or
• the list of the objects represented by one of the fields of the arc (Object field of a node)
*Note: in a path, you can only add fields on its intermediate nodes (not its intermediate arcs).
When the end-user clicks Click to see details (displayed in the arc grouping tooltip), the list of objects is displayed in the Search and Result window.
To set a display on details on an arc grouping:
1. Access the Report Graph Arc properties. The arc is a path.
*Access the Report Graph View and expand its Report Graph Layer concerned, see Accessing the Report Templates and their Constituents.
2. In the Properties window , display its Characteristics page.
3. In the Grouping specifications section, in the Details on field, use the drop-down list to specify the object you want to display.
4. In the Object field, use the drop-down list to select the object.
