Pointers in Xamarin Linear Gauge (SfLinearGauge)
8 Jan 202524 minutes to read
SfLinearGauge provides support to mark the values using BarPointer and SymbolPointer.
Adding bar pointer to scale
BarPointer is used to mark the scale values. It starts at the beginning of gauge and ends at the pointer value.

Setting corner radius type for bar pointer
Corners of the BarPointer can be customized by setting the value to the CornerRadiusType property. All corners of bar pointer can be customized using the Start, End, Both, and None options.
CornerRadius property used to reduce the radius of the corners.

Positioning symbol pointer
You can position the SymbolPointer by using the following two ways:
Setting symbol pointer position
You can customize the position of the SymbolPointer by using the SymbolPointerPosition. The default symbol pointer position is Far.
