The example below demonstrates how to:

<DxChart Data="@WeatherForecasts" CustomizeSeriesPoint="@PreparePointSymbol">
    <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.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;
    }
}
