Setting Diagrams User Preferences

Use the Diagrams tab of the User Preferences window to specify the color-coding used in relationship flow diagrams, the thresholds for clustering and filtering, and performance limits for large diagrams.
  1. Choose Tools > User Preferences. The User Preferences window opens. Click the Diagrams tab.
  2. Select Prompt When Diagram Mode Changes to be prompted when you switch between a diagram generated for a project and a diagram generated for copied-and-pasted objects.
  3. In the Color Scheme pane, click the object type whose color you want to edit. The current background color of the type (if any) is displayed in the Color drop-down.
  4. Click the adjacent Down Arrow Icon button and choose ForeColor from the pop-up menu if you want to specify the color of the caption for the object type, or BackColor if you want to specify the color of the background for the object type.
  5. In the Shape drop-down, select the shape of the object type in the diagram. Select Lock Shape Aspect to specify that the shape not be adjusted to fit the caption.
  6. Click Performance button. The Performance Option Limits dialog opens.
  7. Deselect Relayout Subgraphs if you do not want child groups to be redrawn when you choose a new layout style.
    Note: Selecting this option may result in poor performance for very large diagrams.
  8. In the Maximum relationships to return from repository field, enter the maximum number of relationships to display in the diagram. Relationships are truncated when the maximum is exceeded.
    Note: Setting this option too high may result in poor performance for very large diagrams.
  9. In the Force Symmetric Layout (all relationships) field, enter the maximum number of relationships to display in the diagram before forcing symmetric layout style.
    Note: Symmetric layout style typically offers the best performance for very large diagrams. Setting this option too high may result in poor performance for very large diagrams.
  10. In the Offer Auto Clustering Layout (all relationships) field, enter the maximum number of relationships to display in the diagram before offering to perform clustering.
  11. Select Filter Options Enabled to enable filtering.
  12. In the Hide Drivers (all relationships) field, enter the maximum number of relationships to display in the diagram before filtering drivers. (A driver is an object with many outputs, a startup program, for example.) Specify the filtering thresholds for inputs and outputs:
    • In the Incoming Relationships field, enter the filtering threshold for incoming relationships.
    • In the Outgoing Relationships field, enter the filtering threshold for outgoing relationships.
  13. In the Hide Utilities (all relationships) field, enter the maximum number of relationships to display in the diagram before filtering utilities. (A utility is an object with many inputs, DATEFMT, for example.) Specify the filtering thresholds for inputs and outputs:
    • In the Incoming Relationships field, enter the filtering threshold for incoming relationships.
    • In the Outgoing Relationships field, enter the filtering threshold for outgoing relationships.
  14. In the Hide High Output Nodes (all relationships) field, enter the maximum number of relationships to display in the diagram before filtering objects with many outputs that do not meet the outgoing relationships threshold for drivers. Specify the filtering thresholds for outputs in the Outgoing Relationships field.
  15. In the Hide High Input Nodes (all relationships) field, enter the maximum number of relationships to display in the diagram before filtering objects that do not meet the incoming relationship threshold for utilities. Specify the filtering threshold for inputs in the Incoming Relationships field.
