GraphicItem object (Visio)
Represents a single component part of a data graphic master (a Master object of type visTypeDataGraphic) that is responsible for a specific graphical adornment of the master.
This Visio object or member is available only to licensed users of Visio Professional 2013.
The default property of a GraphicItem object is ID.
GraphicItem objects can be of four types:
- Color by value
- Data bar
- Icon set
- Text callout
You cannot create or significantly modify GraphicItem objects programmatically—you must perform these tasks in the Visio user interface (UI). For more information about creating and modifying data graphics in the UI, search for "data graphic" in Visio end-user Help.
However, the following properties and methods do permit some programmatic modification of GraphicItem objects. In particular, you can modify the position of a graphic item relative to the shape or selection it's associated with, the Z-order (the order in which Visio draws graphic items) of a GraphicItem object in the GraphicItems collection, and the expression (value) used to evaluate a graphic item against the rule that determines how it is displayed.
Use the DataGraphic property to get the Master object of type visTypeDataGraphic that contains the GraphicItem object.
Use the GetExpression method to get the current expression against which the graphic item's rule is evaluated.
Use the SetExpression method to set the current expression against which the graphic item's rule is evaluated.
Use the Delete method to delete a GraphicItem object from the GraphicItems collection.
Use the HorizontalPosition property to get or set the horizontal position of the graphic item relative to the shape or selection that it's associated with.
Use the VerticalPosition property to get or set the vertical position of the graphic item relative to the shape or selection that it's associated with.
Use the UseDataGraphicPosition property to get or set whether a GraphicItem object inherits the settings of the DataGraphicHorizontalPosition and DataGraphicVerticalPosition properties of the data graphic master it belongs to (when set to True), or whether the GraphicItem object's own HorizontalPosition and Vertical Position settings are applied (when set to False).
