The LinearGauge widget 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 option, and then specify the options that are specific to this type, if needed. To learn the options 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 option. 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 option is "vertical".
Specifies the distance between the needle and the center of a gauge for the indicator of a needle-like type.
This option accepts either the name of a predefined palette or an array of colors. The array can include the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
VizPalette enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values:
When you use a twoColorNeedle indicator, define the colors for it using the color and secondColor options. The color option sets the color for the base of the needle. The secondColor option sets the color for the tip of the needle.
In addition, you can specify the ratio between the main and the second color using the secondFraction option.
Different options of the subvalueIndicator configuration object can be set for different types of the subvalue indicators. These options are listed within the Indicator Types section.
