React LinearGauge - subvalueIndicator

Specifies the appearance properties of subvalue indicators.

Selector: SubvalueIndicator
Type:

Object

The LinearGauge UI component can display one main value and several subvalues. The gauge's main value and subvalues are indicated by special pointers. You can customize the appearance of these pointers using the valueIndicator and subvalueIndicator configuration objects correspondingly.

The subvalue indicator is a pointer, which designates an extra value on a scale. There are several types of subvalue indicators. Set the required one by using the type property, and then specify the properties that are specific to this type, if needed. To learn the properties that can be specified for a particular type, refer to one of the following sections.

arrowLength

Specifies the length of an arrow for the indicator of the textCloud type in pixels.

Type:

Number

Default Value: 5
This member is exposed by the following entities:

backgroundColor

Specifies the background color for the indicator of the rangeBar type.

Type:

String

Default Value: 'none'
This member is exposed by the following entities:

This property supports the following colors:

baseValue

Specifies the base value for the indicator of the rangeBar type.

Type:

Number

Default Value: undefined
This member is exposed by the following entities:
Cannot be used in themes.

By default, a range bar starts from the beginning of the gauge scale. If you need to draw the range bar starting from a specific scale value, assign the required value to the baseValue property. In this instance, the range bar will display the range from the baseValue to the main gauge value.

beginAdaptingAtRadius

Specifies a radius small enough for the indicator to begin adapting.

Type:

Number

Default Value: 50
This member is exposed by the following entities:

When adapting, the indicator adjusts its parts and surroundings proportionally to the changing UI component size. The adjustments affect the incidator's indent from the center, the offset from the scale, and the spindle's size and gap.

color

Specifies the color of the indicator.

Selector: Color

This property supports the following colors:

You can also specify a custom pattern or gradient instead of a plain color. Call the registerPattern() or registerGradient() method to obtain a fill ID. Assign that value to the fillId field.
