How to set opacity of the Blazor Chart?

This article explains how to adjust the opacity of the Blazor Chart component.

Changing the opacity of the Blazor Chart using the Opacity property

Blazor Charts supports the customization of series color opacity. By setting the Opacity property of the series value between 0 and 1, you can modify the opacity of the series color.

The following code example illustrates this:

Index.Razor

@using Syncfusion.Blazor.Charts

<SfChart Title="Olympic Medals">

    <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>

    <ChartSeriesCollection>
        <ChartSeries DataSource="@MedalDetails" XName="X" YName="Y" Opacity="0.5" Fill="Green" Type="ChartSeriesType.SplineArea">
            <ChartSeriesBorder Width="2" Color="black"></ChartSeriesBorder>
        </ChartSeries>
    </ChartSeriesCollection>
    
</SfChart>

@code {

    public class ChartData
    {
        public string X { get; set; }
        public double Y { get; set; }
    }

    public List<ChartData> MedalDetails = new List<ChartData>
    {
        new ChartData { X= "South Korea", Y= 39.4 },
        new ChartData { X= "India", Y= 61.3 },
        new ChartData { X= "Pakistan", Y= 20.4 },
        new ChartData { X= "Germany", Y= 65.1 },
        new ChartData { X= "Australia", Y= 15.8 },
        new ChartData { X= "Italy", Y= 29.2 },
        new ChartData { X= "United Kingdom", Y= 44.6 },
        new ChartData { X= "Saudi Arabia", Y= 9.7 },
        new ChartData { X= "Russia", Y= 40.8 },
        new ChartData { X= "Mexico", Y= 31 },
        new ChartData { X= "Brazil", Y= 75.9 },
        new ChartData { X= "China", Y= 51.4 }
    };
