Configuration

An object that defines configuration options for the RangeSelector widget.

background

Specifies the options for the range selector's background.

Type:

Object

A background is an area that is painted in a specified color. You can change this color by setting the background's color property and by displaying an image specified by the image configuration object. In addition, you can superimpose a chart on a background by specifying the chart configuration object. The chart will be shown with the specified background color. To show the chart without a background, set the background's visible property to false.

NOTE
You can use this option only when the range selector displays an image or chart. If not, use the selectedRangeColor and tick to customize the appearance of your widget.

behavior

Specifies the RangeSelector's behavior options.

Type:

Object

chart

Specifies the options required to display a chart as the range selector's background.

Type:

Object

The RangeSelector widget can be created with a chart as the background. In this instance, the range selector can be used for selecting the required range on the chart. At the same time, the Chart widget can be displayed near the range selector and zoomed or scrolled according to the range selected in the range selector. For details on how to synchronize these two widgets, refer to the Zooming and Scrolling topic.

To provide a data source for the chart located in the background, set the dataSource property of the rangeSelectorOptions root configuration object and define the series within the chart configuration object. Set the chart series' argumentField and valueField properties to the corresponding data source fields. The argument field will also be used to create the range selector's scale.

NOTE
You may need to use the rangeValue1Field and rangeValue2Field properties instead of the valueField property if you define range-like series. For the candleStick and stock series types, specific properties should also be specified instead of the valueField property.

The color specified for the range selector's background will also be visible in the chart's background by default. You can change it using the color property of the background configuration object. To prohibit the display of the background color, set the background's visible property to false.

containerBackgroundColor

Specifies the color of the parent page element.

Type:

String

Default Value: '#FFFFFF'

Set this property to the color of the parent page element. Certain RangeSelector elements will use this color to coordinate with the page. For instance, the RangeSelector's shutters use this color, but you can change this color to a custom color.

dataSource

Specifies a data source for the scale values and for the chart at the background.

Cannot be used in themes.

Use this property in the following cases:

  • to initialize a scale with data from one of the data source fields. Set the dataSourceField property to specify which field to use as the source for scale values.
  • to plot a chart using data from the data source fields. In this case, define the chart series by setting their argumentField and valueField properties. The range selector's scale will represent the chart's argument axis. It is created using data from the field specified by the chart's argumentField property.

The maximum and minimum values of the field specified by the argumentField/dataSourceField property are used as the scale's start and end values. The major tick interval is determined automatically. You can also set the interval using the scale's tickInterval and minorTickInterval properties.

For details on how to configure a data source, refer to the Data Binding topic.

dataSourceField

Specifies the data source field that provides data for the scale.

Type:

String

Default Value: 'arg'

Use this property to initialize a scale with data from one of the data source's fields. Set the name of the required data source field to this property.

export

Configures the exporting and printing features.

Type:

Object

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.

indent

Range selector's indent options.

Type:

Object

The indent is used to precisely align scales of several widgets arranged vertically. This is the distance between the container edge and the range selector's scale (see the image below).

RangeSelectorMargin ChartJS

Note that if the indent is set very small, the Scale Labels will be cut.

loadingIndicator

Configures the loading indicator.

Type:

Object

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.

DevExtreme HTML5 Charts LoadingIndicator

To activate the loading indicator, assign true to the loadingIndicator.show option. Once data is loaded, the loading indicator will be hidden automatically.

Type:

String

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.

When using the widget as an ASP.NET MVC Control, specify this option using the VizTheme enum. 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:

Object

|

String

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 selected range, initial or current.

Type:

Array<Number | String | Date>

Raised Events: valueChanged
Cannot be used in themes.

By default, the selected range is the entire scale. To specify a different range to be selected initially, assign an array of two values - start and end - to the value option. Depending on the scale type, these values should be of Numeric, String or Date type.

When using AngularJS/Knockout, bind a scope property/observable value to the value option if you need to get or set this option at runtime. With jQuery only, use the getValue() and setValue(value) methods for the same purpose.
