IClassifyGEN Interface

Provides access to members that control classification.

Product Availability

Description

Classify objects apply one of several methods to statistically subdivide a set of numeric values into classes.

The IClassifyGEN interface is implemented by all the data classification objects (DefinedInterval, EqualInterval, NaturalBreaks, Quantile, StandardDeviation); this is the interface used to pass in histogram data and then classify it into breaks. The ClassID and MethodName properties are used by user interface dialog boxes to identify the classification object and establish what the classification is called.

In general, to classify a dataset, use this interface together with IClassBreaksRenderer. Use the Classify method to add data to the classification; set the number of classes; and generate breaks (typically use the same number of classes specified here for IClassBreaksRenderer.BreakCount). Then apply the classification to the renderer by cycling through ClassBreaks and setting each IClassBreaksRenderer.Break.

Members

	Name	Description
	ClassBreaks	The array of class breaks (double). ClassBreaks(0) is the minimum value in the dataset, and subsequent breaks represent the upper limit of each class.
	ClassID	The CLSID for the classification object.
	Classify	Classifies histogram data (array of values (doubles) and a paired array of frequencies (longs)) into the specified number of classes.
	MethodName	The name of the classification method (based on choice of classification object).

Remarks

The IClassifyGEN interface has been created to use in place of IClassify.
