Style graphics with symbols

Use a symbol style to display a graphic on a graphics overlay.

Use case

Allows you to customize a graphic by assigning a unique symbol. For example, you may wish to display individual graphics for different landmarks across a region, and to style each one with a unique symbol.

How to use the sample

Pan and zoom around the map. Observe the graphics on the map.

How it works

1. Create a GraphicsOverlay object.
2. Create an instance of a Symbol subclass, such as SimpleFillSymbol, SimpleLineSymbol, SimpleMarkerSymbol, or TextSymbol.
3. Create a Graphic instance, specifying a Geometry, attributes, and a Symbol.
4. Add the graphic to the graphics overlay.
5. Create a MapView instance with the graphics overlay.
