To render a multicolored line series, use the series type as MultiColoredLine. Here, the individual colors to the data can be mapped by using PointColorMapping.

        <ChartPrimaryXAxis ValueType="Syncfusion.EJ2.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
  
        <ChartSeriesCollection>
            <ChartSeries DataSource="@MedalDetails" XName="X" YName="Y" PointColorMapping="Color" Type="ChartSeriesType.MultiColoredLine">
            </ChartSeries>
        </ChartSeriesCollection>
</EjsChart>

@code{
    public class ChartData
    {
        public string X;
        public double Y;
        public string Color;
    }
    public List<ChartData> MedalDetails = new List<ChartData> 
    {
        new ChartData { X= "South Korea", Y= 39.4, Color="red" },
        new ChartData { X= "India", Y= 61.3, Color="green" },
        new ChartData { X= "Pakistan", Y= 20.4, Color="#ff0097" },
        new ChartData { X= "Germany", Y= 65.1, Color="crimson" },
        new ChartData { X= "Australia", Y= 15.8, Color="blue" },
        new ChartData { X= "Italy", Y= 29.2, Color="darkorange" },
