Inherited Protected

Name	Visibility	Description
DefinedInterval	public	The interval between class breaks is defined by the user through the Interval property.
EqualInterval	public	The range of attribute values is partitioned into equal-sized subranges by defining the number of classes through the NumClasses property.
GeometricalInterval	public	Class breaks are based on class intervals that have a geometrical series.
KMeans	public	Class breaks are determined using the K-Means Clustering Algorithm.
KMeansSpatial	public	K-Means algorithm is used to partition data into N=NumClasses spatial clusters based on objects centroids.
Manual	public	Class breaks are set manually by the user through the AddClassBreak method.
NaturalBreaks	public	Class breaks are determined using the Fisher's Exact Optimization algorithm.
Quantile	public	Class intervals are created to have an equal number of observations.
Quartile	public	Quantile method is applied with fixed property NumClasses=4.
StandardDeviation	public	Class breaks are set above and below the mean of the attribute values at intervals, for example at 1, 1/2, 1/3, or 1/4 standard deviations until all the data values are contained within these ranges.
StandardDeviationWithCentral	public	Same as StandardDeviation but class breaks are shifted by a half of the interval to get central class in range [Mean-Interval/2..Mean+Interval/2].
Unique	public	Class breaks are set for unique values.
