Hi Leigh,
Thanks for using Syncfusion products.
We have analyzed your query. We would like to inform you that if we would like to change the border color of the Adornment symbol then use we need to use Data Template as shown in the below code snippet.
Code Snippet [XAML]:
<DataTemplate x:Key="adornment">
<Grid>
<Rectangle Fill="#FFF78A09" StrokeThickness="0" Height="30" Width="40">
</Rectangle>
<TextBlock Text="{Binding LabelContent}" Foreground="Black" FontSize="16"/>
</Grid>
</DataTemplate>
<chart:ChartAdornmentInfo ShowLabel="True" SegmentLabelContent="YValue" SegmentLabelFormat="#"
AdornmentsPosition="Top" SymbolTemplate="{StaticResource adornment}"/>
We have prepared a sample based on this and it can be downloaded from the following location.
Please let us know if you have any queries.
Regards,
Muneesh Kumar G.
