Specify Data Attributes

Before you can analyze network data, you must specify which variables to use for node identification, link origin, and termination. For more information about these variables, see About Data Sources.

To specify attributes:

Select DataEdit Attributes. The Edit Data Attributes dialog box opens.

Note: This dialog box opens automatically in response to particular commands. For example, the dialog box opens if you attempt to create a network graph but haven't yet specified the required data attributes.

For link attributes, specify the following:

From	Select the variable that corresponds to the link’s origin node.
To	Select the variable that corresponds to the node at which the link terminates.
Color	(Optional) Select the variable to use for link colors. The link colors vary based on the value of the variable that you select.

For node attributes, specify the following:

ID	Select the variable that identifies the nodes in the data set.
Shape	(Optional) Select the variable to use for the node marker shapes. The shapes vary based on the value of the variable that you select.
Color	(Optional) Select the variable to use for the node marker colors. The colors vary based on the value of the variable that you select.
Label	(Optional) Select the variable to use for the node labels. If you apply labels to nodes in a network graph, the labels are determined by the value of the variable that you select.

Click OK.
