Hi telerik,

We are plotting ScatterlineSeries on a RadCartesianChart. Works well.

However, as we plot several series in same chart, our users request a tooltip with differents units. For example I got the TooltipTemplate following:

<DataTemplate x:Key="MomentTooltipTemplate">
    <Grid Height="56" Width="150" SnapsToDevicePixels="True">
        <Path Data="M0,0 L128.99968,3.4450557E-14 128.99968,36.850185 11,36.850185 8,40 5,36.850185 0,36.850185 z"
    Stretch="Fill"
    Fill="{Binding Presenter, Converter={StaticResource PaletteExtractorConverter}}"
    Stroke="White"
    StrokeThickness="1"
    SnapsToDevicePixels="True" HorizontalAlignment="Center" Width="150" />
        <Grid Margin="5,3,5,9" Height="45" SnapsToDevicePixels="True">
            <Grid.RowDefinitions>
                <RowDefinition Height="15" />
                <RowDefinition Height="15" />
                <RowDefinition Height="15" />
            </Grid.RowDefinitions>
            <TextBlock Text="{Binding DataItem.SeriesName}" Foreground="White" FontFamily="Segoe UI" FontSize="11" VerticalAlignment="Center" Margin="0" />
            <TextBlock Text="{Binding DataItem.Y, ConverterCulture=fr-FR, StringFormat=Load: \{0:N2\} kN.m}" Foreground="White" FontFamily="Segoe UI" FontSize="11" Margin="0" Grid.Row="1" VerticalAlignment="Center" HorizontalAlignment="Left" />
            <TextBlock Text="{Binding DataItem.X, StringFormat=Distance: \{0:N2\} m}" Foreground="White" FontFamily="Segoe UI" FontSize="11" Margin="0" VerticalAlignment="Center" Grid.Row="2" />
        </Grid>
    </Grid>
</DataTemplate>

 

and the second one : 

<DataTemplate x:Key="AnnotationTemplate" DataType="telerik:DataPoint">
                <Grid Height="56" Width="111" SnapsToDevicePixels="True">
                    <Path Data="M0,0 L110,0 110,36.850185 11,36.850185 8,40 5,36.850185 0,36.850185 z"
                Stretch="Fill"
                Fill="{Binding Presenter, Converter={StaticResource PaletteExtractorConverter}}"
                Stroke="White"
                StrokeThickness="1"
                SnapsToDevicePixels="True" />
                    <Grid Margin="4,2,5,10" Width="100" Height="45" SnapsToDevicePixels="True">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="15" />
                            <RowDefinition Height="15" />
                            <RowDefinition Height="15" />
                        </Grid.RowDefinitions>
                        <TextBlock Text="{Binding DataItem.SeriesName}" Foreground="White" FontFamily="Segoe UI" FontSize="11" VerticalAlignment="Center" Margin="0" />
                        <TextBlock Text="{Binding DataItem.Y, StringFormat=Load: \{0:N2\} kg}" Foreground="White" FontFamily="Segoe UI" FontSize="11" Margin="0" Grid.Row="1" VerticalAlignment="Center" />
                        <TextBlock Text="{Binding DataItem.X, StringFormat=Distance: \{0:N2\} m}" Foreground="White" FontFamily="Segoe UI" FontSize="11" Margin="0" VerticalAlignment="Center" Grid.Row="2" />
                    </Grid>
                </Grid>
            </DataTemplate>

 

x axes is the same for all series, but not y axes, for some series y-axe is kg and for some other it's kN.m. See attached files to see what I had and what i'd like.

Is it possible to do that with telerik or not ?

Thanks

 Regards

Hello,

You should be able to use the TooltipTemplate property of the series:
<telerik:LineSeries TooltipTemplate="{StaticResource ...}" />

Thanks, it works.

For people who have the same case, here the piece of code I used :

<controls:RadCartesianChart x:Name="ChartMoment"  TooltipTemplate="{StaticResource MomentTooltipTemplate}" Margin="8,8,220,8">
 
                            <controls:RadCartesianChart.Palette>
