DataFilter Class

Defines specific filter conditions of a particular series.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v18.2.dll

Declaration

C#

public class DataFilter :
    ChartNonVisualElement,
    IDataFilter,
    ICloneable

VB.NET

Public Class DataFilter
    Inherits ChartNonVisualElement
    Implements IDataFilter,
               ICloneable

Remarks

The DataFilter class contains settings that define specific filter conditions to be applied to the corresponding series.

A series maintains instances of the DataFilter class in its Series.DataFilters collection, represented by an object of the DataFilterCollection type.

When one or more data filter objects are created for a series, the series will only be represented within a chart control’s diagram by the data points that meet the filter conditions defined. Filter conditions of several data filter objects are combined using either the AND or OR conjunction operator, specified by the Series.DataFiltersConjunctionMode property of the series.
