RadPieChart Customize Tooltip

[Zohaib]

Hi Telerik Team!

 We are using Telerik Xamarin UI Charts to display RadPieChart. How can we customize the chart Tooltip appearance?

 Any help would be appreciated.

Hi Zohaib,

RadPieChart for Xamarin Forms does not expose API for customizing the tooltip. However, you can create your own custom renderer, which will allow you to get access to the native control and customize the tooltip appearance for each specific platform. You can find out more about creating a custom renderer in this help topic.  You can find the topic dedicated to tooltips in the android chart here and the corresponding one for iOS is here. Note, that in iOS, tooltip is implemented with a trackball with hidden line:

Copy Code

chart.AllowTrackball = true;
chart.Trackball.Line.Hidden = true;
chart.Trackball.Tooltip.PinPosition = TKChartTrackballPinPosition.None;
chart.Trackball.SnapMode = TKChartTrackballSnapMode.ClosestPoint;

Best regards,
