Pointers in Xamarin LinearGauge (SfLinearGauge)

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.

Linear Gauge Bar Pointer customization

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.

Change symbol pointer shapes

Different types of shapes are used in SymbolPointer to mark the pointer value in scale. You can change the shape of SymbolPointer by using the MarkerShape property in pointer.

Setting image shape for symbol pointer

You can achieve the image shape by setting the MarkerShape property to Image and setting image path to ImageSource property in SymbolPointer.

Adding multiple pointers

In addition to the default pointer, you can add n number of pointers to a linear scale by using the Pointers property.
