This sample demonstrates how to highlight a region in an axis using ranges in the circular gauge. The width, corner radius, and start and end range of a range can all be customized.
In this example, you can see how to render and configure the ranges in the circular gauge. Ranges are used to group the axis values, and you can use start, end, color, startWidth, endWidth, radius and roundedCornerRadius properties to customize them. In addition, an axis with multiple ranges is shown in the circular gauge component, as well as options to customize the range properties via the property panel.
More information on the ranges can be found in this documentation section.
