15 Dec 202424 minutes to read
Pointers are used to indicate values on the axis. Value of the pointer can be modified using the
value property.

</style>Needle Pointers
A needle pointer contains three parts, a needle, a cap / knob and a tail. The length of the needle can be
customized by using radius property. The length of the tail can be
customized by using length property. The radius of the cap
can be customized by using radius in cap object. The needle and tail
length takes value either in percentage or pixel.

RangeBar pointer is like ranges in an axis, that can be placed on gauge to mark the pointer value.
RangeBar starts from the beginning of the gauge and ends at the pointer value.

</style>Marker Pointer
Different type of marker shape can be used to mark the pointer value in axis. You can change the marker shape using markerShape property in pointer. Gauge supports the below marker shape.
- Circle
- Rectangle
- Triangle
- InvertedTriangle
- Diamond
We can use image instead of rendering marker shape to denote the pointer value. It can be achieved by setting markerShape to Image and assigning image path to imageUrl in pointer.

The pointers can be dragged along the axis line by clicking and dragging them. To enable or disable the drag functionality for all pointers across all axes, use the enablePointerDrag property. When this property is set to true, all pointers can be dynamically adjusted by dragging. Setting it to false keeps all pointers fixed in their specified positions.

</style>Enabling drag functionality for a specific pointer
To enable or disable the drag functionality for specific pointers along the axis line, use the enableDrag property in the required pointer model.
When the
enableDragproperty is enabled for any individual pointer model, theenablePointerDragproperty becomes ineffective.
The following example demonstrates how to enable the drag functionality for multiple pointers individually.

</style>Animation
Pointer will get animate on loading the gauge, this can be handled by using
animation property in pointer.
The enable property in animation allows you to enable or disable the animation.
The duration property specify the duration of the animation in milliseconds.

</style>Gradient Color
Gradient support allows to add multiple colors in the ranges and pointers of the circular gauge. The following gradient types are supported in the circular gauge.
- Linear Gradient
- Radial Gradient
Linear Gradient
Using linear gradient, colors will be applied in a linear progression. The start value of the linear gradient can be set using the startValue property. The end value of the linear gradient will be set using the endValue property. The color stop values such as color, opacity and offset are set using colorStop property.
The linear gradient can be applied to all pointer types like marker, range bar and needle. To do so, follow the below code sample.

Using radial gradient, colors will be applied in circular progression. The inner circle position of the radial gradient will be set using the innerPosition property. The outer circle position of the radial gradient can be set using the outerPosition property. The color stop values such as color, opacity and offset are set using colorStop property.
The radial gradient can be applied to all pointer types like marker, range bar and needle. To do so, follow the below code sample.
