This property can contain any object reference designating the source, target, or purpose of this Primitive. For example, the Value property can be used to hold an item being rendered. It can hold the value that should be displayed in a tooltip when a user hovers over the Primitive. It can supplemental information to construct an image map of the non-data elements of a chart.
The intent behind any data objects referenced by this property are dependent upon the Layer that added this Primitive to the scene graph. Developers are cautioned only to manipulate the values of Primitives their user-defined layer implementation has assigned. The effects of changing the Value property on a Primitive created by the charting infrastructure are undefined.
