Provides access to members that control histogram objects created from different data sources.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
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.
Members
| Description | ||

CoClasses that implement IBasicHistogram
| CoClasses and Classes | Description |
|---|---|
| BasicTableHistogram | A histogram data structure that is created from table data. Use this to pass data to a classification object. |
| TableHistogram (esriCartoUI) | A histogram data structure that is created from table data. Use this to pass data to a classification object. |
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.
