The CircularGauge 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 about the properties that can be specified for a particular type, refer to one of the following sections.
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.
Specifies the orientation of the rangeBar indicator. Applies only if the geometry.orientation property is "vertical".
Specifies the distance between the needle and the center of a gauge for the indicator of a needle-like type.
When you use a twoColorNeedle indicator, define the colors for it using the color and secondColor properties. The color property sets the color for the base of the needle. The secondColor property sets the color for the tip of the needle.
This property supports the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
- Paint server address
In addition, you can specify the ratio between the main and the second color using the secondFraction property.
Specifies the orientation of the rangeBar indicator. Applies only if the geometry.orientation property is "horizontal".
