public HintBehavior Behavior { get; set; }

Property Value

Type	Description
HintBehavior	The hint behavior.

Remarks

The Hint provides the following behaviors that manage how the chart displays the hint:

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:

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>
</dxc:ChartView>

The code above utilizes the following classes and properties:

Symbols	Description
Hint.Behavior	Gets or sets the behavior of the hint.
TooltipHintBehavior	Defines the tooltip behavior.
Series.HintOptions
SeriesHintOptions	Stores the series’ tooltip settings.

Crosshair Cursor Behavior

The chart shows the hint as the Crosshair Cursor:

Note

The Crosshair Cursor requests data to display from a series and axes. The series provides the Series.HintOptions property to configure what data the series returns. The AxisBase.HintOptions property manages how the hint interacts with the axis.

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

XAML

<dxc:ChartView>
    <dxc:ChartView.Hint>
        <dxc:Hint>
            <dxc:Hint.Behavior>
                <dxc:CrosshairHintBehavior GroupHeaderTextVisible="False"/>
            </dxc:Hint.Behavior>
        </dxc:Hint>
    </dxc:ChartView.Hint>
    <dxc:ChartView.AxisY>
        <dxc:NumericAxisY>
            <dxc:NumericAxisY.HintOptions>
                <dxc:AxisHintOptions LineVisible="False" LabelVisible="False"/>
            </dxc:NumericAxisY.HintOptions>
        </dxc:NumericAxisY>
    </dxc:ChartView.AxisY>
    <dxc:ChartView.Series>
        <dxc:BarSeries>
            <dxc:BarSeries.HintOptions>
                <dxc:SeriesCrosshairOptions PointTextPattern="{}{S}, {A}: {V$0.##}"/>
            </dxc:BarSeries.HintOptions>
        </dxc:BarSeries>
    </dxc:ChartView.Series>
</dxc:ChartView>
