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 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:

  • DevExtreme.AspNet.Data
  • DevExtreme-PHP-Data
  • devextreme-query-mongodb

  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.

• 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.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

Make sure that the showFirstLast option is set to true, so that this option takes effect.

To specify a color for the area inside of the point boundary, use the pointColor option.

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.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

To set a color for the bars indicating the values greater than a winloss threshold, specify the winColor option.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

So that this option takes effect, make sure that the showMinMax option is set to true.

To set a color for the minimum point on a sparkline, specify the minColor option.

To specify a color for the area inside of the point boundary, use the pointColor option.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

Make sure that the showMinMax option is set to true, so that this option takes effect.

To set a color for the maximum point on a sparkline, specify the maxColor option.

To specify a color for the area inside of the point boundary, use the pointColor option.

The widget notifies you of errors and warnings by passing messages to the browser console. Each message contains the incident's ID, a brief description, and a link to the Errors and Warnings section where further information about this incident can be found.

The onIncidentOccurred function allows you to handle errors and warnings the way you require. The object passed to it contains the target field. This field provides information about the occurred incident and contains the following properties:

• id
  The incident's ID. The full list of IDs can be found in the Errors and Warnings section.
• type
  The incident's type: "error" or "warning".
• args
  The argument of the incident's message. Depends on the incident. For example, it may be the name of the data source field that was specified incorrectly, or the name of the option that was not set properly.
• text
  The text passed to the browser's console. Includes the args content, if there is any.
• widget
  The name of the widget that produced the error or warning.
• version
  The used DevExtreme version.

If you place the widget on a page that uses a tag modifying the path (<base>, <iframe>, etc.), some of the widget elements may get mixed up or disappear. To solve this problem, set the pathModified option to true.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

Use the VizPointSymbol enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Circle, Square, Polygon, Triangle, and Cross.

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
});

When this option is set to true, the first and last values are highlighted and painted in the color specified by the firstLastColor option.

When this option is set to true, the minimum and maximum values are highlighted and painted in the colors specified by the minColor and maxColor options correspondingly.

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.

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 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: GenericLight, GenericDark, GenericContrast, GenericCarmine, GenericDarkMoon, GenericSoftBlue, GenericDarkViolet, GenericGreenMist, MaterialBlueLight, MaterialLimeLight, MaterialOrangeLight, MaterialPurpleLight, MaterialTealLight.

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.

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.

To see the sparklines of each type in operation, refer to our Visualization Gallery.

Use the SparklineType enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Line, Spline, StepLine, Area, SplineArea, StepArea, Bar, and WinLoss.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

To set a color for the bars indicating the values that are less than the winloss threshold, specify the lossColor option.

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.
