ChartSeriesPointCustomizationSettings.PointLabel Property

Provides access to the point’s label settings.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor


public IChartSeriesLabel PointLabel { get; }

Property Value

Type Description

The point label.


Use this property in the CustomizeSeriesPoint event handler to specify the label color, position, and visibility.

To define appearance settings that apply to all the labels in a series, use the DxChartSeriesLabel component.


Individual label settings have a priority over the common label settings.

The following example demonstrates how to:

  • use the DxChartSeriesLabel component to specify the position of all labels;
  • use the DxChartSeriesLabelConnector component to customize connectors between data points and labels;
  • handle the CustomizeSeriesPoint event to show only labels whose values are between 25 and 75.

                       ArgumentField="@(i => i.Date.Date)"
                       Name="Temperature, F">
        <DxChartSeriesLabel Position="RelativePosition.Outside">
            <DxChartSeriesLabelConnector Visible="true" Width="3" />

@code {
    WeatherForecast[] ChartData;

    protected override async Task OnInitializedAsync() {
        ChartData = await ForecastService.GetForecastAsync();

    protected void PreparePointLabel(ChartSeriesPointCustomizationSettings pointSettings) {
        double value = (double)pointSettings.Point.Value;
        if (value > 25 && value < 75)
            pointSettings.PointLabel.Visible = true;
