ChartSeriesPointModel.Visible Property

Specifies a series point’s visibility.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v21.1.dll

Declaration

public bool Visible { get; set; }

Property Value

Type Default Description
Boolean

true

true if a series point is visible; otherwise, false.

Remarks

A Chart point’s visibility is specified by the Visible. You can override this value for individual points. For this purpose, handle the CustomizeSeriesPoint event and use the PointAppearance.Visible property to set the new visibility state.

The example below demonstrates how to:

<DxChart Data="@WeatherForecasts" CustomizeSeriesPoint="@PreparePoints">
    <DxChartLineSeries AggregationMethod="@(i => (int)i.Average())"
                       Color="@System.Drawing.Color.Gray"
                       ValueField="@((WeatherForecast i) => i.TemperatureF)"
                       ArgumentField="@(i => i.Date.Date)"
                       Name="Temperature, F">
        <DxChartSeriesPoint Symbol="ChartPointSymbol.Cross" Color="System.Drawing.Color.Gray" Size="15" />
    </DxChartLineSeries>
</DxChart>

@code {
    WeatherForecast[] WeatherForecasts;
    ...
    protected void PreparePoints(ChartSeriesPointCustomizationSettings pointSettings) {
        double value = (double)pointSettings.Point.Value;
        if (value < 75)
            pointSettings.PointAppearance.Visible = false;
    }
}
