Definition

Namespace:

Exposes the FilterDataPoint(DataPoint, Series, Int32) method, which allows Series data to be custom filtered.

public interface class IDataPointFilter
public interface IDataPointFilter
type IDataPointFilter = interface
Public Interface IDataPointFilter

Remarks

The IDataPointFilter interface exposes the FilterDataPoint method, which takes a specific data point within a series and returns a Boolean value that determines whether that data point will be filtered.

To perform custom filtering:

  • Derive a new or existing class from this interface.

  • Override the FilterDataPoint method to provide the custom filtering logic.

  • To initiate the filtering operation, call one of the Filter methods in the DataManipulator class that takes an IDataPointFilter object as its first parameter.

For sample source code, see the FilterDataPoint method.
