Interacting with a Graph
Interacting with a graph involves the following:
•Zooming in and out. You can change the way a graph is displayed by using the zoom function. To zoom in or out, do one of the following:
•Rotate the mouse wheel backward or forward.
•Press and hold the Ctrl key, and then press the plus (+) or minus (-) key.
•Selecting one or more nodes in a graph. You can change the display of a graph to show only selected nodes for further selective analysis on graph data. If nodes are selected, then only those nodes and nodes directly connected to selected nodes are displayed. Unselected nodes become inactive (grayed out). You can select one or more graph nodes by clicking while holding down the Ctrl key.
•Moving one or more nodes in a graph. You can move any node in a graph to a less-occupied section of the screen, while maintaining all its connections (links). To move the selected node, select and drag the node to the desired location.
•Grouping unique contacts. A unique contact is an external user that communicates with one and only one internal user. If desired, you can group together unique contacts (if any) that internal users communicate with. To group all unique contacts for each internal user, right-click the graph, and then click Group unique contacts. The identifiers of the unique contacts (e-mail addresses, social network, and instant messenger IDs) will be placed inside the Unique node for each internal user. The grouping method will help you quickly and easily find unique contacts.
When unique contacts are grouped, applying the Group unique contacts command removes the grouping. As unique contacts are grouped together by default, the first use of that command ungroups the unique contacts. Apply that command once more to restore the grouping of unique contacts.
•Setting a limit for displaying users per one click on a node. You can control how many users are shown in a graph each time when the plus sign (+) on a node is clicked. To configure the number of users to display per one click on a node, right-click in the graph, and then click Populate contacts/users threshold. In the dialog box that opens, select the Populate contacts/users threshold check box, and then, in the Threshold box, type or select the number of users (the default is 20 users). When the threshold is specified, the most communicatively active contacts on the user’s contact list are displayed first. Clicking the plus sign (+) in the top left corner of a user node displays all the user’s remaining contacts. Clicking the minus sign (-) in the bottom right corner of a user node collapses the previously opened user’s contacts.
The limit for displaying users is also applicable to the nodes that represent domains and the Unique nodes. To view the full list, click the plus sign (+) in the top left corner of the node. To return to the limited list, click the minus sign (-) in the bottom right corner of the node.
