    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    Declaration

    public enum ChartSeriesPointSelectionMode

    Members

    Name Description Image
    AllPointsForArgument

    All points that have the same argument are selected when a user selects a point.

    All points with the same argument are selected

    AllPoints

    All points that belong to the series are selected when a user selects a point.

    All points of a series are selected

    Point

    Only a clicked point is selected.

    A single point is selected

    None

    Point selection is disabled.

    Remarks

    Specify the DxChart.PointSelectionMode property to enable point selection at the chart level.

    You can also specify the DxChart.SeriesSelectionMode property to allow users to select entire series.

    Note

    For discrete series (for example, bars), the DxChart.PointSelectionMode property has a higher priority over the DxChart.SeriesSelectionMode property. This means that these properties are not applied simultaneously.

    Example

    The following example enables selection for a line chart:

    • A user can select multiple points. Points with the same argument are selected when the user selects a point.
    • A user can select an entire series by clicking a line segment. When the user selects a series, the selection of the previously selected series is reset.

    Different modes of chart selection are shown
