How to display additional data in Tooltips in UWP Charts?

This article explains how to customize the tooltip content in the UWP Chart by using the TooltipTemplate property. By default, the chart displays only the Y-axis value in the tooltip, but you can modify this behavior to show additional information from your data model.

Step 1: Create a DataModel that includes the properties that you want to display in the tooltip.

public class DataModel
{
    public string Country { get; set; }
    public double Population { get; set; }
}

Step 2: Create a DataTemplate with the key "tooltipTemplate" that defines how the tooltip content should be displayed. The DataContext of the template is the chart segment, from which you can access the corresponding data model through the Item property.

<Page.Resources>
    <DataTemplate x:Key="tooltipTemplate">
        <StackPanel Orientation="Horizontal">
            <TextBlock FontFamily="Segoe UI" Foreground="White">
                  <Run Text="{Binding Item.Country}"/>
                  <Run Text=":"/> 
                  <Run Text="{Binding Item.Population}"/>
            </TextBlock>
        </StackPanel>
    </DataTemplate>
</Page.Resources>

Step 3: Configure the SfChart with appropriate axes and assign the custom tooltip template using the TooltipTemplate property of the series.

<StackPanel>
    <syncfusion:SfChart Header="Population growth">
        <syncfusion:SfChart.PrimaryAxis>
            <syncfusion:CategoryAxis/>
        </syncfusion:SfChart.PrimaryAxis>
        <syncfusion:SfChart.SecondaryAxis>
            <syncfusion:NumericalAxis/>
        </syncfusion:SfChart.SecondaryAxis>
        <syncfusion:ColumnSeries 
                    ItemsSource="{Binding Data}" 
                    XBindingPath="Country" 
                    YBindingPath="Population" 
                    ShowTooltip="True" 
                    TooltipTemplate="{StaticResource tooltipTemplate}"/>
    </syncfusion:SfChart>
</StackPanel>
