Chart for WPF also lets you add some annotations to the chart at specific control co-ordinates. By default, these annotations appear as simple text labels. But, their look and feel can be fully customized using custom templates.

Examples

XAML:

<syncfusion:Chart Name="chart1">
    <!-- Template defining the custom look and feel of the annotations -->
    <syncfusion:Chart.AnnotationLabelTemplate>
        <DataTemplate>
            <Border Background="MintCream" BorderBrush="Black"
BorderThickness="1">
                <TextBlock Text="{Binding}" Foreground="Black"
FontFamily="Tahoma" FontSize="12" Margin="5"/>
            </Border>
        </DataTemplate>
    </syncfusion:Chart.AnnotationLabelTemplate>
    <syncfusion:Chart.AnnotationLabels>
            <!-- ChartAnnotationLabel instance representing the location and
content of the annotation. -->
            <syncfusion:ChartAnnotationLabel x:Name="label1" Content="Top 6
Products" OffsetX="50" OffsetY="60">
            </syncfusion:ChartAnnotationLabel>
    </syncfusion:Chart.AnnotationLabels>
