React CircularGauge Props

An object that defines configuration options for the CircularGauge widget.

animation

Specifies animation options.

Type:

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.

containerBackgroundColor

Specifies the color of the parent page element.

Type:

Default Value: 'none'

Set this property to the color of the parent page element. Certain elements of the widget will use this color so that they coordinate with the page. Currently, different auxiliary separators use the container background color, so there is no need to set a custom color for them.

disabled

Specifies whether the widget responds to the user interaction.

Type:

Default Value: false

Cannot be used in themes.

elementAttr

Specifies the attributes to be attached to the widget's root element.

Type:

Default Value: {}

export

Configures the exporting and printing features.

Type:

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.

NOTE

Safari on Mac OS does not implement an API for saving files. Therefore, exporting in these browsers requires setting up a server-side proxy. For details, refer to the proxyUrl option description.

DevExpress.viz.refreshPaths()

rangeContainer

Specifies gauge range container options.

Type:

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.

Type:

Default Value: true

Cannot be used in themes.

When this option is set to true, the widget will be redrawn automatically in case the size of its parent window changes.

NOTE

To redraw the widget after the size of its container has changed, call the render() method of the widget's instance.

rtlEnabled

Switches the widget to a right-to-left representation.

Type:

Default Value: false

Cannot be used in themes.

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.

JavaScript

DevExpress.config({
    rtlEnabled: true
});

scale

Specifies a gauge's scale options.

Type:

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

Specifies the widget's size in pixels.

Type:

Default Value: undefined

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.

subtitle

Use the subtitle property instead.

Specifies a subtitle for the widget.

Type:

|

Use this property to set the text to be displayed as a gauge subtitle (the text below the title). If you need to specify the subtitle's font, assign an object to the subtitle property with the required options specified. In this instance, set the subtitle's text using the text property. When text is not specified for a subtitle, the widget is displayed without a subtitle.

subvalueIndicator

Specifies the appearance options of subvalue indicators.

Type:

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

Specifies a set of subvalues to be designated by the subvalue indicators.

Type:

Default Value: undefined

Raised Events: onOptionChanged

Cannot be used in themes.

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.

JavaScript

var gaugeOptions = {
    // ...
    subvalues: []    
}

Subvalues are designated by subvalue indicators. You can customize the appearance of these indicators using the subvalueIndicator configuration object.

theme

Sets the name of the theme the widget uses.

Type:

Default Value: 'generic.light'

Accepted Values: 'generic.dark' | 'generic.light' | 'generic.contrast' | 'ios7.default' | 'generic.carmine' | 'generic.darkmoon' | 'generic.darkviolet' | 'generic.greenmist' | 'generic.softblue' | 'material.blue.light' | 'material.lime.light' | 'material.orange.light' | 'material.purple.light' | 'material.teal.light'

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.

NOTE

The following themes were deprecated or renamed: 'desktop', 'desktop-dark', 'android', 'android-holo-light', *android5.light*, 'ios', 'win8', 'win8-white', 'win8.white', 'win8.black', 'win10.white', 'win10.black'. In new applications, use themes listed in the accepted 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

Configures the widget's title.

Type:

tooltip

Configures tooltips.

Type:

A tooltip is a miniature rectangle displaying the value of a gauge's indicator. A tooltip appears when the end-user hovers the cursor over an indicator. You can enable/disable tooltips, change their appearance and format their text using fields of the tooltip configuration object.

value

Specifies the main value on a gauge.

Type:

Default Value: undefined

Raised Events: onOptionChanged

Cannot be used in themes.

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.
