You run Diagram Manager and expect to see all objects but there are only a few objects in the diagram.

To select more objects to appear in the diagram, choose  Tools Hide or Show Items t

You carry out a function that you cannot undo. For example, you draw an arrow incorrectly and it is associated with only an arrowhead on an objective.

To undo a function, choose  Tools Hide or Show Items , hide the objective, close the dialog box, then return into the dialog box and make it visible again. That will get rid of the incorrect arrowhead.

A KPI, objective, or perspective has been removed from the context, but the goal diagram still shows the item.

If the Diagram Manager is open when you update the settings in the Administrator, you must close the Diagram Manager, reopen it, and save the diagram to see the changes reflected in the diagram.
