areaSettings
Use the layers property instead.
The map areas usually represent geographical objects, such as countries, continents, etc. The appearance of these areas is specified by the options of the areaSettings configuration object. If these options are defined on the first level of the areaSettings object, they are applied to all the map areas at once. However, you can specify several of these options for certain areas exclusively. See the customize option description to learn how.
bounds
When you need to display only a specific region on a map, rather than the whole thing, specify the geographical coordinates of this region using the bounds option. Assign an array of four values to this option. These values represent geographical coordinates in the following format: [minLongitude, maxLatitude, maxLongitude, minLatitude]. See the image below to discover how these values are applied to the map.
controlBar
The control bar is a panel on a map that helps you navigate this map. This panel contains the pan control and the zoom bar for panning and zooming the map correspondingly. You can change the visibility of the control bar and adjust its colors using the options of the controlBar configuration object.
elementAttr
Specifies the attributes to be attached to the widget's root element.
jQuery
$(function(){ $("#vectorMapContainer").dxVectorMap({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-vector-map ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-vector-map>
import { DxVectorMapModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxVectorMapModule ], // ... })
ASP.NET MVC Control
@(Html.DevExtreme().VectorMap() .ElementAttr("class", "class-name") // ===== or ===== .ElementAttr(new { @id = "elementId", @class = "class-name" }) // ===== or ===== .ElementAttr(new Dictionary<string, object>() { { "id", "elementId" }, { "class", "class-name" } }) )
@(Html.DevExtreme().VectorMap() _ .ElementAttr("class", "class-name") ' ===== or ===== .ElementAttr(New With { .id = "elementId", .class = "class-name" }) ' ===== or ===== .ElementAttr(New Dictionary(Of String, Object) From { { "id", "elementId" }, { "class", "class-name" } }) )
export
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.

legends[]
A legend is a supplementary map element that helps end-users identify a map area or a map marker. The VectorMap widget can display several legends simultaneously. To configure legends, declare an array of objects and assign it to the legends option. Each object in this array specifies settings of one legend. These settings are described in this section.
Each legend requires the source option to be set. This option specifies whether it is areas or markers that must be accompanied with a legend. Learn more from the description of the source option.
A map legend contains several legend items. A legend item consists of a marker and a text. You can change the size of markers using the markerSize option. To provide texts for legend items, you need to implement the customizeText function.
loadingIndicator
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.
To activate the loading indicator, assign true to the loadingIndicator.show option. Once data is loaded, the loading indicator will be hidden automatically.

markers
Use the dataSource property instead.
Data you need to provide for map markers depends on the type of the markers you use. Generally, you need to declare an array of objects, each of which must hold the coordinates field specifying geographical coordinates of a marker. Additionally, you need to specify the value field (for bubble markers), or the values field (for pie markers), or the url field (for image markers). To display a label for a marker, specify the text field.
For a more comprehensive description of how to provide data for map markers, see the Data for Markers topic.
markerSettings
Use the layers property instead.
A marker is a point on a map accompanied by text that helps you flag places on the map. For example, you can use markers to designate cities on the map. The appearance of the markers is specified by the options of the markerSettings configuration object. If these options are defined on the first level of the markerSettings object, they are applied to all the markers at once. However, you can specify several of these options for certain markers exclusively. See the customize option description to learn how.
