DxChartSeriesLabelConnector Class

Provides settings for series label connectors.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.dll

Declaration

public class DxChartSeriesLabelConnector :
    DxSettingsComponent<ChartSeriesLabelConnectorModel>

Remarks

Use the DxChartSeriesLabelConnector component to display connectors between series points and labels. You can also specify the connector's color and width.

The following example demonstrates how to:

  • define the label position and connector appearance at the series level;
  • show only labels whose values are between 25 and 75.
<DxChart Data="@WeatherForecasts" CustomizeSeriesPoint="@PreparePointLabel">
    <DxChartLineSeries AggregationMethod="@(i => (int)i.Average())"
                       ValueField="@((WeatherForecast i) => i.TemperatureF)"
                       ArgumentField="@(i => i.Date.ToString("yyyy/MM/dd"))"
                       Name="Temperature, F">
        <DxChartSeriesLabel Position="@RelativePosition.Outside">
            <DxChartSeriesLabelConnector Visible="true" Width="3" />
        </DxChartSeriesLabel>
    </DxChartLineSeries>
</DxChart>

@code {
    WeatherForecast[] WeatherForecasts;
    ...
    protected void PreparePointLabel(ChartSeriesPointCustomizationSettings pointSettings)
    {
        double value = (double)pointSettings.Point.Value;
        if(value > 25 && value < 75)
            pointSettings.PointLabel.Visible = true;
    }
}
