Class Graphic
A type of GeoElement that has a shape (geometry), symbol, and attributes and can be displayed in a map view or scene view.
Implements
Namespace: Esri.ArcGISRuntime.UI
Assembly: Esri.ArcGISRuntime.dll
Syntax
public class Graphic : GeoElement, INotifyPropertyChangedRemarks
Graphics are used to represent temporary data that exists for the lifetime of the application. For example, you can:
- Show updated locations for objects in the map view, such as moving vehicles.
- Display results from an analysis, geocoding, or routing operation.
- Allow the user to draw temporary sketches on top of the map.
- Store user input, such as a set of route stops to visit.
- Show ad hoc text labels to describe things on the map.
To display a graphic, add it to a Graphics collection and add the graphics overlay to your map view or scene view.
Each graphic has a geometry describing its location and shape. To maximize performance, the geometry should have the same SpatialReference as the map view or scene view to which it is added. If the geometry has a different SpatialReference, it will be reprojected on-the-fly. This can be computationally expensive when displaying a large number of graphics.
A graphic can have an associated Symbol that defines the graphic's appearance. Alternatively, the GraphicsOverlay can be assigned a Renderer that determines the appearance of all graphics in the overlay. If a graphic has an associated symbol, the symbol will override the overlay's renderer for the graphic's display. The symbol used depends on the geometry type associated with the graphic. A MarkerSymbol is used for MapPoint and Multipoint geometries, a SimpleLineSymbol for Polyline geometries, and a SimpleFillSymbol for Polygon or Envelope geometries.
You can select or deselect graphics (IsSelected), change the visibility of a graphic (IsVisible), and manage the order in which they are displayed (ZIndex).
