Remarks
This interface exposes the FilterDataPoint method, which takes a specific data point within a series and then returns a boolean value that determines if the data point will be filtered.
To perform custom filtering:
- Derive a new or existing class (e.g. the WebForm class) from this interface.
- Override the FilterDataPoint method to provide the custom filtering logic.
- To initiate the filtering operation call the Filter method and use one of the definitions that takes an IDataPointFilter object as its first parameter.
For sample source code see the FilterDataPoint topic.
