An IntervalItem node defines an interval bound used to categorize markers on a vector map.
An example of using the IntervalItem node is provided in the Display Areas on a Vector Map topic.
This interface is a part of the Application Model infrastructure and is not intended to be implemented by your classes. The IModelIntervalItem is used by the Maps Module, to extend the IModelVectorMapSettings node. To learn more, refer to the Application Model Structure topic.
