Properties
asyncBindings
Allows you to override the global WjOptions.asyncBindings setting for this specific component. See the WjOptions.WjOptions.asyncBindings property description for details.
binding
Gets or sets the binding for the layer.
The binding can include two comma-separated property names (longitude and latitude) 'lon,lat' or a single property name that contain a pair of geographical coordinates.
colorScale
Gets or sets color scale used for fill layer's items.
initialized
This event is triggered after the component has been initialized by Angular, that is all bound properties have been assigned and child components (if any) have been initialized.
isInitialized
Indicates whether the component has been initialized by Angular. Changes its value from false to true right before triggering the initialized event.
itemsSource
Gets or sets a data source for the layer.
Data source should be a collection of objects that provides geographical coordinates (longitude and latitude). Object property or properties which contains coordinates are specified by binding property.
itemsSourceChangePC
This event is used to implement two-way binding to the itemsSource property. It's triggered when the property value changes, with the event argument holding the new property value. You can bind handlers to this event in templates using the itemsSourceChange event name.
itemsSourceChangedNg
Angular (EventEmitter) version of the Wijmo itemsSourceChanged event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional itemsSourceChanged Wijmo event name.
map
Gets the parent map
style
Gets or sets the layer's style.
symbolMaxSize
Gets or sets the maximal symbol size.
For bubble plot.
symbolMinSize
Gets or sets the minimal symbol size.

wjProperty
Gets or sets a name of a property that this component is assigned to. Default value is 'layers'.
Methods
created
-
If you create a custom component inherited from a Wijmo component, you can override this method and perform necessary initializations that you usually do in a class constructor. This method is called in the last line of a Wijmo component constructor and allows you to not declare your custom component's constructor at all, thus preventing you from a necessity to maintain constructor parameters and keep them in synch with Wijmo component's constructor parameters.

Returns Rect
initialize
