How to display more data in the tooltip in WinUI Chart (SfCartesianChart)?
The WinUI Chart control offers support for displaying detailed information from its data source using the Tooltip UI customization feature. This is achieved with the TooltipTemplate within the chart series. Below is an example that shows how to display both a country's name and its population details in the tooltip. By default, the tooltip displays the corresponding y-axis value of the segment.
[Xaml]
<chart:SfCartesianChart Header="Population Growth">
<chart:SfCartesianChart.DataContext>
<local:ViewModel/>
</chart:SfCartesianChart.DataContext>
<chart:SfCartesianChart.Resources>
<ResourceDictionary>
<DataTemplate x:Key="tooltipTemplate">
<StackPanel Orientation="Horizontal">
<!-- Template element has DataContext as its Segment named Item. From it, you can access the corresponding Model -->
<TextBlock FontFamily="Segoe UI" Foreground="White">
<Run Text="{Binding Item.Country}"/>
<Run Text=":"/>
<Run Text="{Binding Item.Population}"/>
</TextBlock>
</StackPanel>
</DataTemplate>
</ResourceDictionary>
</chart:SfCartesianChart.Resources>
<chart:SfCartesianChart.XAxes>
<chart:CategoryAxis/>
</chart:SfCartesianChart.XAxes>
<chart:SfCartesianChart.YAxes>
<chart:NumericalAxis/>
</chart:SfCartesianChart.YAxes>
<chart:ColumnSeries ItemsSource="{Binding Data}"
XBindingPath="Country"
YBindingPath="Population"
EnableTooltip="True"
TooltipTemplate="{StaticResource tooltipTemplate}">
</chart:ColumnSeries>
</chart:SfCartesianChart>Output
