Add Graphics with Renderer

Specify a graphic's symbol with a renderer.

A renderer allows you to change the style of all graphics in an overlay by only changing one copy of the symbol. A renderer will only effect graphics that do not specify their own symbol.

How it works

To show a Graphic in a GraphicsOverlay using a renderer:

  1. Create a GraphicsOverlay and add it to the MapView
  2. Create a Graphic, specifying only its geometry
  3. Create a single Symbol such as a SimpleMarkerSymbol
  4. Create a renderer with the symbol such as new SimpleRenderer(symbol)
  5. Set the renderer on the graphics overlay with graphicsOverlay.setRenderer(renderer)
