Radius

You can place the range inside or outside of the axis by using radius property. The radius of the range can takes value either in percentage or in pixels. By default, ranges take 100% of the axis radius.

In Pixel

You can set the radius of the range in pixel as demonstrated below,

};

In Percentage

By setting value in percentage, range gets its dimension with respect to its axis radius. For example, when the radius is ‘50%’, range renders to half of the axis radius.

Multiple Ranges

You can add multiple ranges to an axis with the above customization as demonstrated below.

Note: You can set the range color to axis ticks and labels by enabling useRangeColor property in majorTicks, minorTicks and labelStyle object.

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.

To apply linear gradient to the range, follow the below code sample.

Radial Gradient

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.

To apply radial gradient to the range, follow the below code sample.
