NaturalBreaks CoClass

Defines a natural breaks classification method.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

The NaturalBreaks coclass uses a statistical formula to determine natural clusters of attribute values. The formula is known as Jenk�s method. This attempts to minimize the variance within a class and to maximize the variance between classes. The natural-breaks classification is well suited to uneven distributions of attributes. Distinct natural groupings of attributes can be isolated and highlighted.

This classification only uses the IClassify interface, so there is nothing to set up other than calling IClassify::SetHistogramData.

Supported Platforms

Windows, Solaris, Linux
