How to disable series visibility on initial rendering in Blazor Charts?

This article explains how to disable series visibility on initial rendering.

Disabling Series Visibility by Default

Blazor Charts provides an option to disable chart series visibility at initial load using its Visible property.

This can be achieved by specifying the Visible property as false for the required series to be disabled and assigning a Name for the disabled series to view it in the legend. Then, by toggling the legend, the series visibility can be changed.

The code example below demonstrates how to disable series visibility by default.

Index.razor:

@using Syncfusion.Blazor.Charts
<SfChart>
   <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
   <ChartSeriesCollection>
       <ChartSeries Name="Gold" Fill="#E94649" Visible="false" DataSource="@MedalDetails" XName="X" YName="YValue" Type="Syncfusion.Blazor.Charts.ChartSeriesType.Column">
       </ChartSeries>
       <ChartSeries Name="Silver" Fill="#F6B53F" DataSource="@MedalDetails" XName="X" YName="YValue1" Type="Syncfusion.Blazor.Charts.ChartSeriesType.Column">
       </ChartSeries>
   </ChartSeriesCollection>
</SfChart>
@code{
   public class ChartData
   {
       public string X { get; set; }
       public double YValue { get; set; }
       public double YValue1 { get; set; }
   }
   public List<ChartData> MedalDetails = new List<ChartData>
   {
       new ChartData { X= "USA", YValue= 46, YValue1=56 },
       new ChartData { X= "GBR", YValue= 27, YValue1=17 },
       new ChartData { X= "CHN", YValue= 26, YValue1=36 },
       new ChartData { X= "UK", YValue= 56,  YValue1=16 },
       new ChartData { X= "AUS", YValue= 12, YValue1=46 },
       new ChartData { X= "IND", YValue= 26, YValue1=16 },
       new ChartData { X= "DEN", YValue= 26, YValue1=12 },
       new ChartData { X= "MEX", YValue= 34, YValue1=32},
   };
} 

The following screenshot illustrates the output of the code snippet.
