This article explains how to change the legend position in Blazor Chart Component.

Customize the legend position

You can change the position of the legend using the Position property in ChartLegendSettings. By default, the legend position is set to Auto, which is determined by the area type of the chart.

The Position property includes the following options:

Auto - Places the legend based on the area type.
Top - Displays the legend at the top of the chart.
Bottom - Displays the legend at the bottom of the chart.
Right - Displays the legend at the right of the chart.
Left - Displays the legend at the left of the chart.
Custom(using X and Y coordinates) - Displays the legend based on the given x and y values.

In the following code example, the legend can be positioned at the left by using the Position property.

@using Syncfusion.Blazor.Charts

<SfChart Title="Olympic Medals">
    <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" />
