Interface IBasicHistogram

All Superinterfaces:

Serializable

All Known Implementing Classes:

BasicTableHistogram, TableHistogram

public interface IBasicHistogram
extends Serializable

Provides access to members that control histogram objects created from different data sources.

Description

Use BasicTableHistogram::ITableHistogram 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.

Remarks

IBasicHistogram performs a function similar to IHistogram, but it is available to Engine developers. Use IBasicHistogram with a BasicTableHistogram like you would use IHistogram with a TableHistogram.

Product Availability

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

Method Summary

boolean	getHistogram(Object[] doubleArrayValues, Object[] longArrayFrequencies) Histogram as an array of values (doubles) and a paired array of frequencies (longs).
void	invalidate() Causes to recreate the Histogram from the Table for the next GetHistogram call.
void	resetCustomMinMax() Resets custom minimum and maximum.
void	setCustomMax(double rhs1) Custom maximum.
void	setCustomMin(double rhs1) Custom minimum.
