Tooltip Behavior

The chart shows the hint as a tooltip:

NOTE

The Tooltip requests data to display from a series. The series provides the Series.HintOptions property to configure what data the series returns.

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

<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>

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

<dxc:ChartView>
    <dxc:ChartView.Hint>
        <dxc:Hint>
            <dxc:Hint.Behavior>
                <dxc:CrosshairHintBehavior GroupHeaderTextVisible="False"/>

        </dxc:Hint>
    </dxc:ChartView.Hint>
    <dxc:ChartView.AxisY>
        <dxc:NumericAxisY>
