IGenerateStatistics Interface

Provides access to members used for generating statistics.

Product Availability

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

Description

IGenerateStatistics is used after cocreating a BaseStatistics object directly rather than getting one from IDataStatistics::Statistics. You populate the object with data using the AddValue method before returning statistics. Always set the SimpleStats property to True, unless you want frequency statistics (see IFrequencyStatistics).
