Hi Andreas,

We can resolve the reported problem by setting ChartTrackBallBehavior UseSeriesPalette property value as true for multiple combination chart as per in the below code example.

…

<chart:SfChart.Behaviors>

    <chart:ChartTrackBallBehavior UseSeriesPalette="True"/>

</chart:SfChart.Behaviors>

Output:


(OR)

By using the custom template for the series trackball label using TrackBallLabelTemplate property as per in the below code example.

<chart:SfChart.Resources>

    <DataTemplate x:Key="lineTemplate">

        <TextBlock Foreground="Black" Text="{Binding Item.YValue}" FontSize="10"/>

    </DataTemplate>

 

    <DataTemplate x:Key="candleTemplate">

        <StackPanel Margin="4" Orientation="Vertical">

            <Grid>

                <Grid.ColumnDefinitions>

                    <ColumnDefinition Width="Auto"/>

                    <ColumnDefinition Width="Auto"/>

                </Grid.ColumnDefinitions>

                <TextBlock Text="High : " FontSize="10"/>

                <TextBlock Padding="3,0,0,0" FontSize="10" Grid.Column="1" Text="{Binding Item.High}"/>

            </Grid>

            …

        </StackPanel>

    </DataTemplate>

</chart:SfChart.Resources>

 

…

<chart:CandleSeries ItemsSource="{Binding StockPriceDetails}"

                    High="High" Low="Low"

                    Close="Close" Open="Open"

                    XBindingPath="Date"

                    TrackBallLabelTemplate="{StaticResource candleTemplate}"/>

 

<chart:LineSeries ItemsSource="{Binding Data}"

                  XBindingPath="XValue" YBindingPath="YValue"

                  TrackBallLabelTemplate="{StaticResource lineTemplate}"/>
