IFrequencyStatistics Interface

Provides access to members used for reporting frequency statistics.

Product Availability

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

Description

IFrequencyStatistics is used to return information about your data values that is similar to an equal-interval histogram. You can use ComputeAutoFrequencyIntervals to let the system choose a suitable data interval, or set it manually with the FrequencyIntervalCount property. Retrieve the frequency values with FrequencyClassCount, which uses a zero-based index.

You can QI to IFrequencyStatistics after calling IDataStatistics::Statistics as long as IDataStatistics::SimpleStats is False.
