This Visio object or member is available only to licensed users of Visio Professional 2013.
A data graphic is a Master object of type visTypeDataGraphic. When the same master that is already applied to a shape is re-applied to the shape, the ShapeDataGraphicChanged event does not fire, even if the master has been modified since it was applied originally. If, however, a different data graphic master is applied to the shape, the event does fire.
If you're using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.
If you want to create your own Event objects, use the Add or AddAdvise method. To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection. To create an Event object that receives notification, use the AddAdvise method. To find an event code for the event you want to create, see Event codes.
