The following code configures this hint behavior and manages how the hint interacts with this series:

XAML

<dxc:ChartView>
    <dxc:ChartView.Hint>
        <dxc:Hint>
            <dxc:Hint.Behavior>
                <dxc:TooltipHintBehavior/>
            </dxc:Hint.Behavior>
        </dxc:Hint>
    </dxc:ChartView.Hint>
    <dxc:ChartView.Series>
        <dxc:BarSeries>
            <dxc:BarSeries.HintOptions>
                <dxc:SeriesHintOptions PointTextPattern="{}{S}, {A}: {V$0.##}"/>
            </dxc:BarSeries.HintOptions>
        </dxc:BarSeries>
    </dxc:ChartView.Series>
