Remarks

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

The following code snippet demonstrates how to:

use the DxChartSeriesPoint component to define the common point appearance;
handle the CustomizeSeriesPoint event to change the symbol of points whose values are greater than 75.

razor

<DxChart Data="@WeatherForecasts" CustomizeSeriesPoint="@PreparePointSymbol">
    <DxChartLineSeries SummaryMethod="@(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.Polygon" Color="System.Drawing.Color.Gray" Size="25" />
    </DxChartLineSeries>
</DxChart>

@code {
    WeatherForecast[] WeatherForecasts;
    ...
    protected void PreparePointSymbol(ChartSeriesPointCustomizationSettings pointSettings) {
        double value = (double)pointSettings.Point.Value;
        if (value > 75)
            pointSettings.PointAppearance.Symbol = ChartPointSymbol.Cross;
    }
}
