This sample visualizes pointer drag in circular gauge. Position of pointer value can be changed by using Pointer Value and we can drag the pointer by enabling drag option.
In this example, you can see how to move pointers in gauge using drag and drop. Use enablePointerDrag property, to achieve this behavior.
In this sample, you can drag the pointer using mouse or touch, the pointer value will be updated in an annotation placed in the gauge.
More information on the gauge can be found in this documentation section.
