Validating Data

SAS/GRAPH Network Visualization Workshop validates data in order to ensure that the data contains the required variables. Validation also checks whether the data sets contain observations and whether there are duplicate nodes in the node data. If the node data contains duplicate nodes, SAS/GRAPH Network Visualization Workshop prompts you to either keep or delete the duplicates. Regardless of your choice, the underlying data set is unchanged. The next time you update your data, it is recommended that you remove the duplicate nodes from your node data set.

The data’s NODE ID, FROM, and TO variables must be assigned before the data can be validated. If you attempt to validate data whose variables have not been assigned, then SAS/GRAPH Network Visualization Workshop opens the Edit Data Attributes dialog box. For details about using this dialog box, see Specify Data Attributes.

SAS/GRAPH Network Visualization Workshop validates data automatically when it synchronizes the data. You can also validate your data manually.

To validate data manually:

If your data has already been validated, then the menu item is dimmed, indicating that it is not available.
