Position and alignment
Legend Position
The legend can be placed at Left, Right, Top, Bottom or Custom position of the chart using the Position property. By default, the legend appears at the bottom of the chart.
@using Syncfusion.Blazor.Charts
<SfChart Title="Olympic Medals">
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"/>
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" Name="Gold" XName="Country" Width="2" Opacity="1" YName="Gold" Type="ChartSeriesType.Column"/>
<ChartSeries DataSource="@MedalDetails" Name="Silver" XName="Country" Width="2" Opacity="1" YName="Silver" Type="ChartSeriesType.Column"/>

</SfChart>
@code{
public class ChartData
{
public string Country { get; set; }
public double Gold { get; set; }
public double Silver { get; set; }
public double Bronze { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData{ Country= "USA", Gold=50, Silver=70, Bronze=45 },
new ChartData{ Country="China", Gold=40, Silver= 60, Bronze=55 },
new ChartData{ Country= "Japan", Gold=70, Silver= 60, Bronze=50 },
new ChartData{ Country= "Australia", Gold=60, Silver= 56, Bronze=40 },
new ChartData{ Country= "France", Gold=50, Silver= 45, Bronze=35 },
new ChartData{ Country= "Germany", Gold=40, Silver=30, Bronze=22 },
new ChartData{ Country= "Italy", Gold=40, Silver=35, Bronze=37 },
new ChartData{ Country= "Sweden", Gold=30, Silver=25, Bronze=27 }
};
}
The Custom position helps to position the legend anywhere in the chart using x and y coordinates.

Legend customization
Legend Shape
The LegendShape property in the Series can be used to change the shape of the legend icon. The default icon shape for legends is SeriesType.
@using Syncfusion.Blazor.Charts
<SfChart Title="Olympic Medals">
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" />
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" Name="Gold" XName="Country" Width="2" Opacity="1" YName="Gold" Type="ChartSeriesType.Column" LegendShape="LegendShape.Circle"/>
<ChartSeries DataSource="@MedalDetails" Name="Silver" XName="Country" Width="2" Opacity="1" YName="Silver" Type="ChartSeriesType.Column" LegendShape="LegendShape.SeriesType"/>
<ChartSeries DataSource="@MedalDetails" Name="Bronze" XName="Country" Width="2" Opacity="1" YName="Bronze" Type="ChartSeriesType.Column" LegendShape="LegendShape.Diamond"/>
</ChartSeriesCollection>
<ChartLegendSettings Visible="true" />
</SfChart>
@code{
public class ChartData
{
public string Country { get; set; }
public double Gold { get; set; }
public double Silver { get; set; }
public double Bronze { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData{ Country= "USA", Gold=50, Silver=70, Bronze=45 },
new ChartData{ Country="China", Gold=40, Silver= 60, Bronze=55 },
new ChartData{ Country= "Japan", Gold=70, Silver= 60, Bronze=50 },
new ChartData{ Country= "Australia", Gold=60, Silver= 56, Bronze=40 },
new ChartData{ Country= "France", Gold=50, Silver= 45, Bronze=35 },
new ChartData{ Country= "Germany", Gold=40, Silver=30, Bronze=22 },
new ChartData{ Country= "Italy", Gold=40, Silver=35, Bronze=37 },
new ChartData{ Country= "Sweden", Gold=30, Silver=25, Bronze=27 }
};
}
Legend Size
When the legend is placed on the top or bottom of the chart, it takes up 20% - 25% of the chart’s height, and 20% - 25% of the chart’s width when it is positioned on the left or right side of the chart. So, the Width and Height properties can be used to adjust the default legend size.
