Changing marker symbol in Blazor Chart

Blazor Chart provides data markers to adorn the data points with different shapes and labels. It is enabled by setting Visible Property of ChartMarker to true.

The default shape of data marker in Blazor Chart is Circle. It can be assigned different shapes such as Rectangle, Circle, Diamond etc., by using the Shape property.

The following code illustrates how to use the Shape property to change the data marker symbol.

@using Syncfusion.Blazor.Charts

<SfChart>
    <ChartSeriesCollection>
        <ChartSeries DataSource="@ConsumerReports" XName="X" YName="Y" Type="ChartSeriesType.Line">
            <ChartMarker Visible="true" Height="10" Width="10" Shape="ChartShape.Diamond"/>
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>

@code {
    public class ChartData
    {
        public double X { get; set; }
        public double Y { get; set; }
    }

    public List<ChartData> ConsumerReports = new List<ChartData>
    {
