Labeled Column Series Chart in Wpf

Why don't you change the Template of the ColumnDataPoint inside the DataPointStyle similar to here

             <charting:ColumnSeries Height="350" Foreground="Black"                    ItemsSource="{Binding Path=MyCurrentResultsView.ResultsView}"                    IndependentValueBinding="{Binding Key}"                    DependentValueBinding="{Binding Value}"><charting:ColumnSeries.DataPointStyle>    <Style TargetType="charting:ColumnDataPoint">        <Setter Property="Template">            <Setter.Value>             <ControlTemplate TargetType="charting:ColumnDataPoint">             <Grid>                <Rectangle Fill="{TemplateBinding Background}" Stroke="Black"/>                <Grid Margin="0 -20 0 0" HorizontalAlignment="Center" VerticalAlignment="Top">                    <TextBlock Text="{TemplateBinding FormattedDependentValue}" Margin="2"/>                </Grid>             </Grid>             </ControlTemplate>            </Setter.Value>        </Setter>    </Style></charting:ColumnSeries.DataPointStyle> 

How about something like this:
