Hello Andreas,

We have created the data template in the code behind and set it to the series ToolTipTemplate property as shown in the code snippet. We have also attached a sample for your reference.

dataTemplate = new DataTemplate(() =>

{

    VerticalStackLayout mainlayout = new VerticalStackLayout();

    mainlayout.BackgroundColor = Colors.Black;

 

    HorizontalStackLayout yearLayout = new HorizontalStackLayout();

    yearLayout.BackgroundColor = Colors.Black;

 

    Label yearLabel = new Label() { Padding = 2, FontSize = 10, TextColor = Colors.White, Text = "Year:" };

    Label year = new Label() { Padding = 2, FontSize = 10, TextColor = Colors.White};

    year.SetBinding(Label.TextProperty, "Item.Year");

    yearLayout.Add(yearLabel);

    yearLayout.Add(year);

 

    HorizontalStackLayout revenueLayout = new HorizontalStackLayout();

    revenueLayout.BackgroundColor = Colors.Black;

 

    Label revenueLabel = new Label() { Padding = 2, FontSize = 10, TextColor = Colors.White, Text = "Revenue:" };

    Label revenue = new Label() { Padding = 2, FontSize = 10, TextColor = Colors.White };

    revenue.SetBinding(Label.TextProperty, "Item.Revenue", stringFormat: "{0}$");

    revenueLayout.Add(revenueLabel);

    revenueLayout.Add(revenue);

 

    mainlayout.Add(yearLayout);

    mainlayout.Add(revenueLayout);

 

    return mainlayout;

});

 

areaSeries.TooltipTemplate = dataTemplate;

Output:

Best Regards,
Raja.
