MapObject

Type class

Baseclass for MapArea, MapLine and MapImage, it overwrites the default settings from AreasSettings, LinesSettings and ImagesSettings.

Example

```js var map = AmCharts.makeChart("mapdiv",{ ... "dataProvider": { "map": "worldHigh", "areas": [ { "id": "LT", "showAsSelected": true } ], "lines": [ { "latitudes": [51.5002, 50.4422], "longitudes": [-0.1262, 30.5367] } ], "images": [ { "type": "circle", "top": 100, "left": 100 } ] } });```

Properties

#accessibleLabel

Type string

Text which screen readers will read if user rolls-over the object or sets focus using tab key (this is possible only if tabIndex property of object settings or individual object is set to some number). Text is added as aria-label tag. Note - not all screen readers and browsers support this.

#alpha

Type number

Opacity of map object.

#balloonText

Type string

Text which is displayed in a roll-over balloon. You can use the following tags: title, description, value and percent.

To disable the balloons, set it to an empty string.

#bringForwardOnHover

Type boolean

Specifies if the object should change it's z-index to the top-most when user hovers it.

#color

Type color

Color of MapObject

#customData

Type object

A custom data holder.

#description

Type string

Description of MapObject. Description is displayed in DescriptionWindow (when user clicks on an object). It can also be displayed in a roll-over balloon. DescriptionWindow can display HTML formatted code.

#descriptionWindowBottom

Distance from the bottom side of map container to the description window. In case it is not set (also if descriptionWindowTop is not set), window will be placed near the mouse pointer.

#descriptionWindowHeight

Type number

Height of description window.

#descriptionWindowLeft

Type number

Distance from the left side of map container to the description window. In case it is not set (also if descriptionWindowRight is not set), window will be placed near the mouse pointer.

#descriptionWindowRight

Distance from the right side of map container to the description window. In case it is not set (also if descriptionWindowLeft is not set), window will be placed near the mouse pointer.

#descriptionWindowTop

Type number

Distance from the top side of map container to the description window. In case it is not set (also if descriptionWindowBottom is not set), window will be placed near the mouse pointer.

#descriptionWindowWidth

Type number

Width of description window.

#fixedSize

Type booleanDefault true

Specifies if the object should change the size together with the map or keep fixed size. This applies for objects with lat and long properties set, as they move together with the map.

#groupId

Type string

Id of a group. You can group MapObjects to groups. Grouped objects will change color together with this object when you roll-over it or click it. You can show/hide them using showGroup(groupId) and hideGroup(groupId) methods of AmMap class. You can also use map.zoomToGroup(groupId) methot to zoom-in the map so that all grouped objects are visible.

#id

Type string

Unique id of the object. In case it's area, id should match svg path id from SVG file. Id can be used with linkToObject property of MapObject - you can link one object to another using it.

#images

Type MapImage[]

Array of MapImage objects.

#lines

Type MapLine[]

Array of MapLine objects.

#linkToObject

Type MapObject

linkToObject can be a reference or id of some other MapObject - MapArea, MapImage or MapLine. It can also be a reference to another DataSet (but not an id). Then user clicks on this object the application would zoom-in to this objects' zoom position (if it is set) and then act as if the linkToObject was clicked. This can also be used for selecting the object you want to be selected right after the map is initialized, as DataSet extends MapObject class, you can specify linkToObject for your DataSet. When you link to another DataSet, you can build drill-down maps.

#mouseEnabled

Type booleanDefault true

Set this to false to make the object be irresponsive to any interactions like hover or click events.

#passZoomValuesToTarget

Type booleanDefault false

Specifies if current zoom values should be passed to target MapObject. Useful when building drill down maps.

#remainVisible

Type booleanDefault true

Specifies if the MapObject and other objects of the same level should remain visible if it was clicked and it has children MapObjects.

#rollOverColor

Type color

Roll over color of of the object.

#selectable

Type booleanDefault false

Specifies if the object can be selected even if it is not clickable. Map object is clickable if zoom properties are set or it has description or has children objects. Sometimes even non of the listed conditions is met you might need it to be clickable. You should set this property to true in this case.

#selectedColor

Type color

Color of an object when it is selected (somebody clicked on it).

#showAsSelected

Type booleanDefault false

Specifies if selectedColor should be applied to the object. AmMap can have only one selected item at a time, however there might be situations when multiple objects (areas, images, lines) have to look like they are selected. By setting this property to true, you will be able to produce this result.

#showInList

Type boolean

Specifies if this object must be displayed in ObjectsList Title should be defined in order the object to appear there.

#tabIndex

Type number

In case you set it to some number, the map will set focus on this object when user clicks tab key. When a focus is set, screen readers like NVDA Screen reader will read label which is set using accessibleLabel property of object settings or individual object. If object is clickable, pressing Enter/Return while focus is set will select the object. Note, not all browsers and readers support this.

#title

Type string

Title of a MapObject. It can be displayed in the roll-over balloon and in the header of description window. All areas in SVG maps distributed with amMap has country names (titles) hard coded in the SVG file.

#url

Type string

Url of an object. The application will go to this url when you click on the object.

#urlTarget

Type stringDefault _self

Target of an URL, if URL is a string, for example: "_blank", "_top".

#useTargetsZoomValues

Type booleanDefault false

If set to true the map will carry over the same zoom values when transitioning to new data provider. Useful when building drill down maps.

#zoomLatitude

Type number

Specifies latitude to which map should be moved when this object is clicked

#zoomLevel

Type number

Specifies map scale to which map should be rescaled when this object is clicked.

#zoomLongitude

Type number

Specifies longitude to which map should be moved when this object is clicked.

#zoomX

Type number

Specifies X position (in percents of stage width) to which map should be moved when this object is clicked. You can also use zoomLat and zoomLong instead of zoomX and zoomY.

#zoomY

Type number

Specifies Y position (in percents of stage height) to which map should be moved when this object is clicked. You can also use zoomLat and zoomLong instead of zoomX and zoomY.
