Hi Leigh,
Thanks for using Syncfusion Products.
We can achieve your requirement by setting Text as per the below code snippet.
Code Snippet[XAML]:
<DataTemplate x:Key="ToolTipTemplate">
<Grid>
<StackPanel>
…………
<TextBlock Text="{Binding
YData}" Margin="0,2,10,0" FontSize="14.666" Foreground="White" FontFamily="Segoeui"
VerticalAlignment="Center"
HorizontalAlignment="Left"
/>
</StackPanel>
</Grid>
</DataTemplate>
We have modified your sample based on this and you can
find the sample under the following location:
