A hint is a small pop-up rectangle that shows information about a tapped series or point. The pie chart displays its hints as tooltips.

How to: Enable Hints in the Pie Chart

2. Set the Enabled property to True.
3. Use the ShowMode property to specify a gesture on which the pie chart shows the hint.

XAML

<dxc:PieChartView>
  <!--...-->
  <dxc:PieChartView.Hint>
    <dxc:PieHint Enabled="True" ShowMode="OnTap" />
  </dxc:PieChartView.Hint>
</dxc:PieChartView>

How to: Customize the Hint Appearance

This example shows how to customize the appearance of pie chart hints. To do this, assign a PieHintStyle object with the specified properties to the PieHint.Style property:

XAML

<dxc:PieChartView>
    <dxc:PieChartView.Hint>
        <dxc:PieHint Enabled="True" ShowMode="OnTap">
            <dxc:PieHint.Style>
                <dxc:PieHintStyle BackgroundColor="#424651"
                                  MarkerSize="30"
                                  Padding="15,15,10,10"
                                  TextIndent="20"/>
            </dxc:PieHint.Style>
        </dxc:PieHint>
