Apply an Overlay to a Cell

You can apply overlays (one overlay at a time) to the cells of the Relationship Matrix. After you select the required overlay in the 'Overlays' field, you can:

  • Apply an overlay value or values to a cell that identifies an existing relationship
  • Create a new relationship in a cell, and immediately apply overlay values to that relationship
  • Change the overlay values currently applied, or
  • Remove the overlay from the cell

A relationship of the selected type is created between the source and target elements, and the selected overlay values are displayed in the cell.
