Configuration

This section describes options that configure the Sankey widget's contents, behavior and appearance.

See Also

adaptiveLayout

Specifies adaptive layout options.

Type:

Object

The adaptive layout enables the widget to hide optional elements if they do not fit in the container. Elements are hidden in the following sequence:

  1. Title
  2. Export menu icon
  3. Labels (can be saved by setting the adaptiveLayout.keepLabels option to true)

Use the height and width options in the adaptiveLayout object to specify the minimum container size at which the layout begins to adapt.

alignment

Aligns node columns vertically.

Type:

String

|

Array<String>

Default Value: 'center'
Accepted Values: 'bottom' | 'center' | 'top'

A string value aligns all node columns uniformly. An array of strings allows you to align each node column individually. For example, the Sankey widget contains four columns, and the alignment option is specified as follows:

jQuery
JavaScript
$(function() {
    $("#sankeyContainer").dxSankey({
        // ...
        alignment: ["top", "bottom", "bottom"]
    });
});
Angular
HTML
TypeScript
<dx-sankey ...
    [alignment]="['top', 'bottom', 'bottom']">
</dx-sankey>
import { DxSankeyModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxSankeyModule
    ],
    // ...
})

With this setting, the leftmost node column is aligned to the top, and the next two columns are aligned to the bottom. The rightmost column does not have a value in the alignment array and is aligned to the center (according to the default value).

Use the VerticalAlignment 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: Bottom, Center, and Top.

dataSource

Binds the widget to data.

Cannot be used in themes.

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

The Sankey works with collections of objects.

Depending on your data source, bind the Sankey to data as follows. In each case, also specify the sourceField, targetField, and weightField 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.

    jQuery
    JavaScript
    $(function() {
        let serviceUrl = "https://url/to/my/service";
        $("#sankeyContainer").dxSankey({
            // ...
            dataSource: DevExpress.data.AspNet.createStore({
                key: "ID",
                loadUrl: serviceUrl + "/GetAction",

        }
    }
    export default App;
  • Any other data source
    Implement a CustomStore.

Regardless of the data source on the input, the Sankey 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:

  • If you wrap the store into the DataSource object explicitly, set the paginate option to false to prevent data from partitioning.

  • 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.

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.

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:

Boolean

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

sortData

Specifies nodes' sorting order in their columns.

Type:

Object

Default Value: undefined

The sorting order depends on the node's weight: the heavier the node, the lower it is in the column. All nodes have the same weight initially (equals 1).

For example, without the sortData object, source nodes in the following code would be sorted as declared in the data source (top to bottom): Australia, New Zealand, Japan. Weights in the sortData object specify the following sorting order: New Zealand, Japan, Australia.

jQuery
JavaScript
$(function() {
    $("#sankeyContainer").dxSankey({
        dataSource: [
            { source: "Australia", target: "Portugal", weight: 5 },
            { source: "New Zealand", target: "Portugal", weight: 1 },
            { source: "Japan", target: "Senegal", weight: 3 }
        ],
        sortData: { "Australia": 3, "New Zealand": 1, "Japan": 2 }
    });
});

sourceField

Specifies which data source field provides links' source nodes.

Type:

String

Default Value: 'source'

targetField

Specifies which data source field provides links' target nodes.

Type:

String

Default Value: 'target'

theme

Sets the name of the theme the widget uses.

Type:

String

Default Value: 'generic.light'
Accepted Values: 'generic.dark' | 'generic.light' | 'generic.contrast' | '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.

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.

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.

tooltip

Configures tooltips - small pop-up rectangles that display information about a data-visualizing widget element being pressed or hovered over with the mouse pointer.

Type:

Object

weightField

Specifies which data source field provides links' weights.

Type:
