Class BasicTableHistogram

java.lang.Object
  com.esri.arcgis.carto.BasicTableHistogram

All Implemented Interfaces:

IBasicHistogram, IDataNormalization, ITableHistogram, com.esri.arcgis.interop.RemoteObjRef, IStatisticsResults, Serializable

public class BasicTableHistogram
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IBasicHistogram, ITableHistogram, IDataNormalization, IStatisticsResults

A histogram data structure that is created from table data. Use this to pass data to a classification object.

Remarks

BasicTableHistogram is used to produce a histogram data structure based on input from an object that supports ITable. This data structure is commonly used as input to the classification coclasses (e.g. NaturalBreaks, Quantile). Use this object if you are developing against only ArcEngine components. The BasicTableHistogram performs a simliar function to TableHistogram, but unlike TableHistogram , it is available to ArcEngine developers.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux
