Detailed Description

Graphics are displayed on the map through a graphics overlay. Common uses of graphics include providing input to a task, displaying output from a task, or marking a location based on user interaction with the map.

Each graphic must contain a geometry describing the location and the shape of the graphic. The geometry preferably should be in the same spatial reference as the map, otherwise it will be reprojected on-the-fly (computationally expensive for large number of graphics).

A graphic can be associated with a symbol which determines how the graphic looks. Alternatively, the graphics overlay can be assigned a renderer which determines the appearance of all graphics in the overlay. If the graphic has an associated symbol, that symbol will override the renderer when displaying that graphic. The symbol used depends upon the geometry type associated with the graphic. A MarkerSymbol is used for point and multipoint geometries, LineSymbol for polyline geometries, and FillSymbol for polygon geometries.

A graphic can contain a list model of attributes (key-value pairs) providing more information about the graphic.

This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

Example:

Create a graphic (JavaScript):

var point = ArcGISRuntimeEnvironment.createObject("Point", {x: -117, y: 34, spatialReference: Factory.SpatialReference.createWgs84()});
var simpleMarker = ArcGISRuntimeEnvironment.createObject("SimpleMarkerSymbol", {color: "black", size: 12, style: Enums.SimpleMarkerSymbolStyleCircle});
var graphic = ArcGISRuntimeEnvironment.createObject("Graphic", {symbol: simpleMarker, geometry: point});
graphic.attributes.insertAttribute("region", "Southern California");
