Cannot be used in themes.

If you use DevExtreme ASP.NET MVC Controls, refer to the Data Binding article.

The Sparkline works with collections of objects.

Depending on your data source, bind the Sparkline to data as follows. In each case, also specify the argumentField and valueField options.

Data Array
Assign the array to the dataSource option. View Demo
Read-Only Data in JSON Format
Set the dataSource option to the URL of a JSON file or service that returns JSON data.
OData
Implement an ODataStore.

Web API, PHP, MongoDB
Use one of the following extensions to enable the server to process data according to the protocol DevExtreme widgets use:

Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.

$(function() {
    let serviceUrl = "https://url/to/my/service";

        );
    }
}
export default App;

Any other data source
Implement a CustomStore.

Regardless of the data source on the input, the Sparkline always wraps it in the DataSource object. This object allows you to sort, filter, group, and otherwise shape data. To get its instance, call the getDataSource() method.

NOTE

Please review the following notes about data binding:

Data field names should not contain the following characters: ., ,, :, [, and ].
DataSource and stores provide methods to process and update data. However, the methods do not allow you to perform particular tasks (for example, replace the entire dataset, reconfigure data access at runtime). For such tasks, create a new array, store, or DataSource and assign it to the dataSource option as shown in the articles about changing options in jQuery, Angular, React, and Vue.

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.

size

Specifies the widget's size in pixels.

Type:

Default Value: undefined

By default, the widget occupies the entire area of the container. If you need to set a particular size for the widget, different from the container's size, assign a height and width in pixels to height and width properties of the size object.

Using the size object, you can hide the widget. For this purpose, simply assign 0 to both the height and width of the widget.

NOTE

The size configuration object reserves space for the main widget elements, while displaying a tooltip may require extra space. To reserve the area around the widget for the tooltip, you can apply a margin to the widget's container.

theme

Sets the name of the theme the widget uses.

Type:

Default Value: 'generic.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: 'android5.light', 'win8.white', 'win8.black', 'win8.light', 'win8.dark', 'win10.white', 'win10.black', 'win10.light', 'win10.dark'. 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.

tooltip

Configures the tooltip.

Type:

A tooltip is a miniature rectangle displaying widget data. The tooltip appears when the end-user hovers the cursor over the widget. You can enable/disable the tooltip, change its appearance and format its text using fields of the tooltip configuration object.

NOTE

The tooltip is displayed outside the widget's container. If you plan to use the tooltip, make sure there is enough space around your widget to display it. For example, you can apply a margin to the widget's container to reserve the area around the widget for the tooltip.

type

Determines the type of a sparkline.

Type:

View Area Sparkline Demo View Bar Sparkline Demo View Winloss Sparkline Demo

Default Value: 'line'

A sparkline type determines the visual representation of data. Different options of the Sparkline widget are available for different types. The table below reflects options that can be configured for the sparkline of a certain type.
