How to use SymbolPointer

I just found the SymbolPointer and tried to use it to Display Minimum and Maximum values on a
gauge. But when I use it, Visual Studio tells me that a conversion of  "Syncfusion.SfGauge.XForms.SymbolPointer" 
to "Syncfusion.SfGauge.XForms.Pointer" is not possible.

Here is my code:

SfCircularGauge circularGauge = new SfCircularGauge();

circularGauge.HorizontalOptions = LayoutOptions.CenterAndExpand;

Scale scale = new Scale();

scale.StartValue = 0;

scale.EndValue = 100;

scale.Interval = 10;

scale.StartAngle = 135;

scale.SweepAngle = 270;

scale.RimThickness = 20;

scale.RimColor = Color.FromHex("#FB0101");

scale.MinorTicksPerInterval = 4;

NeedlePointer needlePointer = new NeedlePointer();

needlePointer.Color = Color.White;

needlePointer.KnobColor = Color.White;

needlePointer.Thickness = 5;

needlePointer.KnobRadius = 20;

needlePointer.LengthFactor = 0.8;

needlePointer.SetBinding(NeedlePointer.ValueProperty, "Pressure");


SymbolPointer minPointer = new SymbolPointer();

minPointer.Color = Color.Red;

minPointer.SetBinding(SymbolPointer.ValueProperty, "Min");


What am I doing wrong?

Hi Jens,

Thanks for your interest in Syncfusion products.

As of now, SymbolPointer is not available in SfCircularGauge control for Xamarin. Instead other two types (RangePointer and NeedlePointer) of pointers can be added to CircularScale in SfCircularGauge, to know more about it, please refer the below UG link.

SymbolPointer support is available in SfLinearGauge for Xamarin, where SfLinearGauge and SfDigitalGauge also shares the same namespace (“Syncfusion.SfGauge.XForms”) with SfCirularGauge. To know more about our linear gauge control, refer the below UG link.

Please let us know, if you have any query.

Are there any plans to add Symbol pointer support for Xamarin Forms users?

Hi Steve, 
Yes we have plans to provide Symbol Pointer in the Circular Gauge control Xamarin.Forms, we have logged a feature request for this and it will be implemented in any of our upcoming release. 
It can be tracked through our Features Management System:
