Specifies the appearance options of the value indicator.
The value indicator is a pointer which designates the main value of the gauge. There are four types of value indicators in the dxCircularGauge widget: rectangleNeedle, triangleNeedle, twoColorNeedle and rangeBar. Different options of the valueIndicator configuration object can be used for each type. Refer to the type option description for information on the available options by types.
In this example, several options of the valueIndicator configuration object are changed. Here, the gauge value is indicated by a two-color needle. The appearance of this needle is customized using the color, secondColor and width options. In addition, the look of the spindle is altered using the spindleSize and spindleGapSize options.
Specifies the background color for the value indicator of the rangeBar type.
Specifies the base value for the value indicator of the rangeBar type.
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 option. In this instance, the range bar will display the range from the baseValue to the main gauge value.
