annotations[]

Specifies the annotation collection.

Selector: dxi-annotation
Type:

Array<VectorMap Annotation | any>

Annotations are containers for images, text blocks, and custom content that display additional information about the visualized data.

DevExtreme VectorMap: Annotations

To create annotations, assign an array of objects to the annotations[] property. Each object configures an individual annotation. You can set each annotation's type property to "text", "image", or "custom". Depending on the type, specify the annotation's text, image, or template property:

jQuery
index.js
$(function() {
    $("#vectorMap").dxVectorMap({
        annotations: [{
            type: "text",
            text: "Annotation text"
        }, {
            type: "image",
            image: "http://image/url/myimage.png"
        }, {
            type: "custom",
            template: function(annotation) {
                const data = annotation.data;
                const $svg = $("<svg>");
                // ...
                // Customize the annotation's markup here
                // ...
                return $svg;
            }
        }]
    });
});

                render={CustomAnnotation}
            />
        </VectorMap>
    );
}

Annotations can be positioned at specific geographic coordinates or coordinates of the client area:

  • Geographic coordinates

    annotations: [{
    coordinates: [-75.4999, 43.00035]
}]

  • Client area coordinates (x and y)

    annotations: [{
    x: 100,
    y: 200
}]

When a user long-presses an annotation or hovers the mouse pointer over it, the VectorMap displays a tooltip.

Objects in the annotations[] array configure individual annotations. To specify properties common for all annotations, use the commonAnnotationSettings object. Individual settings take precedence over common settings.

background

Specifies the properties for the map background.

Selector: dxo-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, specify the geographical coordinates of this region using the bounds property. Assign an array of four values to this property. These values represent geographical coordinates in the following format: [minLongitude, maxLatitude, maxLongitude, minLatitude] with the default range of longitude [-180, 180] and latitude [-90, 90]. See the image below to review how these values are applied to a map.

ChartMargin ChartJS

If your dataSource contains coordinates in a different range, implement a custom projection.

NOTE
Specifying the bounds property 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 UI component 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.

commonAnnotationSettings

Specifies settings common for all annotations in the VectorMap.

Selector: dxo-common-annotation-settings
Type:

Object

Settings specified here can be ignored in favor of individual annotation settings specified in the annotations[] array. Refer to the array's description for information on how to configure annotations.

The following code shows the commonAnnotationSettings declaration syntax:

jQuery
index.js
$(function() {
    $("#vectorMap").dxVectorMap({
        // ...

layers

Specifies properties for VectorMap UI component layers.

Selector: dxi-layer
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.

Selector: dxi-legend
Type:

Array<Legend>

Default Value: undefined

A legend is a supplementary map element that helps end-users identify a map area or a map marker. The VectorMap UI component can display several legends simultaneously. To configure legends, declare an array of objects and assign it to the legends property. Each object in this array specifies settings of one legend. These settings are described in this section.

Each legend requires the source property to be set. This property specifies whether it is areas or markers that must be accompanied with a legend. Learn more from the description of the source property.

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 property. To provide texts for legend items, you need to implement the customizeText function.

Setting this property to false disables a user to pan the map. However, you still can pan the map in code using the center(centerCoordinates) and viewport(viewportCoordinates) methods.

pathModified

Notifies the UI component that it is embedded into an HTML page that uses a tag modifying the path.

Type:

Boolean

Default Value: false
Cannot be used in themes.

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

projection

Specifies the map projection.

Selector: dxo-projection
Type:

VectorMapProjection

|

VectorMapProjectionConfig

|

String

|

Object

Default Value: 'mercator'
Cannot be used in themes.

You can use one of the following out-of-the-box projections:

To set a custom projection, implement two functions (from and to) that convert coordinates from geographical to UI component coordinate systems. The to callback is executed to render initial data in VectorMap. The from callback is called when a user executes the pan or move action. The from and to callbacks should have the same ratio:

JavaScript
 const projection = {
    from: ([x, y]) => [x * A, y * B],
    to: ([lon, lat]) => [lon / A, lat / B],
};

In addition, specify the projection's aspectRatio.

redrawOnResize

Specifies whether to redraw the UI component when the size of the container changes or a mobile device rotates.

Type:

Boolean

Default Value: true
Cannot be used in themes.

When this property is set to true, the UI component will be redrawn automatically in case the size of its container changes.

rtlEnabled

Switches the UI component to a right-to-left representation.

Type:

Boolean

Default Value: false
Cannot be used in themes.

When this property is set to true, the UI component 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
DevExpress.config({
    rtlEnabled: true
});
NOTE
In a right-to-left representation, SVG elements have the direction attribute with the rtl value. This might cause problems when rendering left-to-right texts. Use this property if you have only right-to-left texts.

size

Specifies the UI component's size in pixels.

Selector: dxo-size
Type: viz/core/base_widget:BaseWidgetSize
Default Value: {height: 400, width: 800}

You can specify a custom width and height for the component:

Fixed Relative
Assign values to the size object's height and width properties or specify a container for the component. Specify a container for the component. The component occupies the container area.
NOTE
The size object has priority over the container.

$(function() {
    $("#vectorMapContainer").dxVectorMap({
        // ...
        size: {

    render() {
        return (
            <VectorMap ...
                id="vectorMap">
            </VectorMap>
        );
    }
}
export default App;
#vectorMap {
    width: 85%;
    height: 70%;
}

theme

Sets the name of the theme the UI component uses.

Type:

Theme

Default Value: 'generic.light'

A theme is a UI component configuration that gives the UI component a distinctive appearance. You can use one of the predefined themes or create a custom one. Changing the property values in the UI component's configuration object overrides the theme's corresponding values.

title

Configures the UI component's title.

Selector: dxo-title
Type: viz/core/base_widget:BaseWidgetTitle

The UI component'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 property. Otherwise, set this property 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.

Selector: dxo-tooltip
Type:

Tooltip

A tooltip is a miniature rectangle displaying data of an area or a marker. A tooltip appears when the end-user hovers the cursor over an area or a marker. To show tooltips, do the following.

  • Enable tooltips.
    Set the enabled property to true.

  • Specify text to be displayed in tooltips. Specify the customizeTooltip property.

You can also change the appearance of tooltips using fields of the tooltip configuration object.

View Demo

touchEnabled

Specifies whether the map should respond to touch gestures.

Type:

Boolean

Default Value: true

Assign false to this property if your map is not supposed to be viewed on touch-enabled devices.

wheelEnabled

Specifies whether or not the map should respond when a user rolls the mouse wheel.

Type:

Boolean

Default Value: true

Rolling the mouse wheel zooms a map. If you need to disable this capability, assign false to the wheelEnabled property. A user will still be able to zoom the map using the control bar.

zoomFactor

Specifies a number that is used to zoom a map initially.

Type:

Number

Default Value: 1
Cannot be used in themes.

Use this property to specify a zoom factor for a map while configuring it. This property accepts a value that is greater than 1. Note that the zooming is performed with relation to the center of the map.

zoomingEnabled

Disables the zooming capability.

Type:

Boolean

Default Value: true

Setting this property to false disables a user's ability to zoom the map. However, you can still zoom the map in code using the zoomFactor(zoomFactor) method.
