dataSource
Binds the widget to data.
If you use DevExtreme ASP.NET MVC Controls, refer to the Bind Controls to Data 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 DemoRead-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.
jQuery
JavaScript$(function() { let serviceUrl = "https://url/to/my/service"; $("#sparklineContainer").dxSparkline({ // ... dataSource: DevExpress.data.AspNet.createStore({ key: "ID", loadUrl: serviceUrl + "/GetAction", insertUrl: serviceUrl + "/InsertAction", updateUrl: serviceUrl + "/UpdateAction", deleteUrl: serviceUrl + "/DeleteAction" }) }) });

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.
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.
elementAttr
Specifies the attributes to be attached to the widget's root element.
jQuery
$(function(){ $("#sparklineContainer").dxSparkline({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });

Specifies whether the sparkline should ignore null data points.
Data points that have the null value do not produce actual points. Because of this, the sparkline may be drawn with unnecessary gaps where missing points should have been. To remove these gaps, set the ignoreEmptyPoints option to true.

- Predefined SVG colors
To set a color for the bars indicating the values that are less than the winloss threshold, specify the lossColor option.
winlossThreshold
Specifies a value that serves as a threshold for the sparkline of the winloss type.
In the winloss sparkline, values are represented by bars that either grow up or go down from an invisible line. This line is determined by a threshold value. If a data source value is greater than this threshold value, the bar grows up. Otherwise, it goes down.
You can paint the 'win' and 'loss' bars differently. For this purpose, specify the required colors using the winColor and lossColor options respectively.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
We appreciate your feedback.
