How to: Add a Custom Legend Items to a Legend

Jun 07, 2019

To add a custom legend item to a legend, create a new instance of the CustomLegendItem class and add it to the LegendBase.CustomItems collection. Then, configure the custom item, for example, using the CustomLegendItem.Text property to set the item’s text and the CustomLegendItem.MarkerTemplate property to set the item’s marker.

View Example

MainWindow.xaml

xaml

<Window.Resources>
    <DataTemplate x:Key="markerTemplate">
        <Image Source="Images/DXLogo.png"/>
    </DataTemplate>
</Window.Resources>
        <dxc:ChartControl.Legend>
            <dxc:Legend ItemVisibilityMode="AutoGeneratedAndCustom">
                <dxc:Legend.CustomItems>
                    <dxc:CustomLegendItem MarkerBrush="#FFFF8000" 
                                          MarkerTemplate="{Binding Source={StaticResource markerTemplate}}" 
                                          Text="Powered by DevExpress"/>
                </dxc:Legend.CustomItems>
            </dxc:Legend>
        </dxc:ChartControl.Legend>
