Vue VectorMap Props

An object that specifies configuration options for the widget.

areaSettings Deprecated

Use the layers property instead.

An object specifying options for the map areas.

Type:

Object

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.

background

Specifies the options for the map background.

Type:

Object

The map background is a space on a map that does not contain areas. Within the background configuration object you can specify colors for the map background and its border.

bounds

Specifies the positioning of a map in geographical coordinates.

Type:

Array<Number>

Default Value: undefined
Cannot be used in themes.

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.

ChartMargin ChartJS

NOTE
Specifying the bounds option with the { minLon: minLongitude, maxLat: maxLatitude, maxLon: maxLongitude, minLat: minLatitude } object is now deprecated.

center

Specifies the geographical coordinates of the center for a map.

Type:

Array<Number>

Default Value: [0, 0]
Cannot be used in themes.

By default, the map in the widget is centered on the (0, 0) point. If you need to center the map on a different geographical point, assign an array of two values in the [longitude, latitude] form.

controlBar

Specifies the options of the control bar.

Type:

Object

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.

Type:

Object

Default Value: {}

You can configure this option in an ASP.NET MVC Control as follows:

Razor C#
Razor VB
@(Html.DevExtreme().WidgetName()
    .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().WidgetName() _
    .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

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
IE9 and Safari on Mac OS do 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.

layers

Specifies options for VectorMap widget layers.

Type:

Array<Object>

|

Object

Default Value: undefined
Cannot be used in themes.

The vector map may contain several different layers. Each layer can be of "area", "line" or "marker" type.

The Z-order of layers depends on their order in the layers array in the following way: the first layer occupies the background, the last layer is brought to the foreground.

View Demo

legends[]

Configures map legends.

Type:

Array<Object>

Default Value: undefined

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.

View Demo

loadingIndicator

Configures the loading indicator.

Type:

Object

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.

DevExtreme HTML5 Charts LoadingIndicator

To activate the loading indicator, assign true to the loadingIndicator.show option. Once data is loaded, the loading indicator will be hidden automatically.

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 Deprecated

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.
