JavaScript/jQuery CircularGauge Options
animation
To make your gauge "live", enable animation for it by setting the enabled option of the animation object to true. In this instance, the gauge indicators will appear in motion. In addition, within the animation object, you can set an appropriate easing mode using the easing option and specify how long the animation should run using the duration option.
elementAttr
Specifies the attributes to be attached to the widget's root element.
jQuery
$(function(){ $("#circularGaugeContainer").dxCircularGauge({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-circular-gauge ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-circular-gauge>
import { DxCircularGaugeModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxCircularGaugeModule ], // ... })
ASP.NET MVC Control
@(Html.DevExtreme().CircularGauge() .ElementAttr("class", "class-name") // ===== or ===== .ElementAttr(new { @id = "elementId", @class = "class-name" }) // ===== or ===== .ElementAttr(new Dictionary<string, object>() { { "id", "elementId" }, { "class", "class-name" } }) )
@(Html.DevExtreme().CircularGauge() _ .ElementAttr("class", "class-name") ' ===== or ===== .ElementAttr(New With { .id = "elementId", .class = "class-name" }) ' ===== or ===== .ElementAttr(New Dictionary(Of String, Object) From { { "id", "elementId" }, { "class", "class-name" } }) )
export
These features allow a user to export your widget into a document or print it. When exporting is enabled, the "Exporting/Printing" button appears in the widget. A click on it invokes a drop-down menu that lists exporting and printing commands. The following formats are supported for exporting into: PNG, PDF, JPEG, SVG and GIF.

geometry
Specify the startAngle and endAngle options of the geometry configuration object to customize the shape of the circular gauge's arc. This arc is drawn from the startAngle to the endAngle as it is illustrated by the following image.
loadingIndicator
When the widget visualizes local data, loading is instant. But when the widget is bound to a remote data source, loading may takes a considerable amount of time. To keep the viewer's attention, the widget can display a loading indicator.
To activate the loading indicator, assign true to the loadingIndicator.show option. Once data is loaded, the loading indicator will be hidden automatically.

rangeContainer
For the purpose of more intelligible data visualization, you can combine values into ranges and color each range differently. For instance, you can indicate the range of warm and cold temperatures. To set the ranges, assign an array of objects defining the ranges to the ranges property of the rangeContainer configuration object. In addition, you can specify the orientation of the ranges relative to an invisible scale line, and an offset from this line using the rangeContainer properties.
redrawOnResize
Specifies whether to redraw the widget when the size of the parent browser window changes or a mobile device rotates.
When this option is set to true, the widget will be redrawn automatically in case the size of its parent window changes.
rtlEnabled
When this option is set to true, the widget text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.
DevExpress.config({ rtlEnabled: true });
scale
To divide a scale, set its startValue and endValue properties. The scale's major and minor ticks will be calculated automatically. Major ticks will be shown by default. To show minor ticks, set their visible property to true. You can set custom major and minor tick intervals, show custom major and minor ticks, and format tick labels. These and other scale options are available in the scale configuration object.
size
The widget occupies its container's entire area by default. Use the size object to specify the widget's size if it should be different from that of its container. Assign 0 to size object's height and width options to hide the widget.
jQuery
$(function() { $("#circularGaugeContainer").dxCircularGauge({ // ... size: { height: 300, width: 600 } }); });
Angular
<dx-circular-gauge ... > <dxo-size [height]="300" [width]="600"> </dxo-size> </dx-circular-gauge>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { // ... }

Vue
<template> <dx-circular-gauge ... > <dx-size :height="300" :width="600" /> </dx-circular-gauge> </template> <script> import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import DxCircularGauge, { DxSize } from 'devextreme-vue/circular-gauge'; export default { components: { DxCircularGauge, DxSize }, // ... } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import CircularGauge, { Size } from 'devextreme-react/circular-gauge'; class App extends React.Component { render() { return ( <CircularGauge ... > <Size height={300} width={600} /> </CircularGauge> ); } } export default App;
subvalueIndicator
The CircularGauge 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 about the options that can be specified for a particular type, refer to one of the following sections.
subvalues
In addition to one main value, you can indicate several extra values on a gauge. These are called subvalues. To specify the subvalues, assign an array with them to the subvalues field.
You can obtain and change the subvalues at runtime. In order to do this, use the subvalues() and subvalues(subvalues) methods. Note that in that case, you need to initialize the subvalues option at least with an empty array.
var gaugeOptions = { // ... subvalues: [] }
Subvalues are designated by subvalue indicators. You can customize the appearance of these indicators using the subvalueIndicator configuration object.
theme
A theme is a widget configuration that gives the widget a distinctive appearance. Use can use one of the predefined themes or create a custom one. Changing the option values in the widget's configuration object overrides the theme's corresponding values.
Use the VizTheme
enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: GenericLight
, GenericDark
, GenericContrast
, GenericCarmine
, GenericDarkMoon
, GenericSoftBlue
, GenericDarkViolet
, GenericGreenMist
, IOS7Default
, MaterialBlueLight
, MaterialLimeLight
, MaterialOrangeLight
, MaterialPurpleLight
, MaterialTealLight
.
title
The widget's title is a short text that usually indicates what is visualized. If you need to specify the title's text only, assign it directly to the title option. Otherwise, set this option to an object with the text and other fields specified.
The title can be accompanied by a subtitle elaborating on the visualized subject using the title.subtitle object.
value
The main value is designated by the value indicator. To customize the appearance of the value indicator, use the valueIndicator configuration object.
You can obtain and change the gauge value at runtime. In order to do this, use the value() and value(value) methods.
Only one main value can be indicated on a gauge. Besides the main gauge value, you can indicate several extra values. Refer to the subvalues option description for more information.
