Defining the intersections for a custom matrix (Utilities profile)
1. Open the Custom Matrix's Property Pages.
2. Click the CustomSimpleMatrix tab.
3. If you want an intersection to show a relationship from a row item to a column item, set the tagged value of the rowToColumnIntersectionRole tag definition to the name of the Modeler Automation Interface role you want to use.
If you want an intersection to show a relationship from a column item to a row item, set the tagged value of the columnToRowIntersectionRole tag definition to the name of the Modeler Automation Interface role you want to use.
For example, if you wanted an intersection to show dependency relationships from the row items to the column items, you would set the tagged value of the rowToColumnIntersectionRole tag definition to Dependee.
For information about what roles are available through the Modeler Automation Interface for the different item types, see the Automation Interface and TellMe Utility section of the Modeler Help. Note that the roles are called associations in the Modeler Automation Interface Help.
4. By default, an X is shown for intersections in the Matrix. If you want to use the value of a relationship instead, set the tagged value of the cellDisplayProperty tag definition to the Name of the property you want to use.
For example, if you set the tagged value of the cellDisplayProperty tag definition to Name, an intersection will show the name of the relationship item that links the row and column items.
After defining the intersections for a Custom Matrix, you can open the Custom Matrix. For more information, see Opening a custom matrix (Utilities profile).
