Scene Properties Expressions

Demonstrates how to update the orientation of a graphic using scene property rotation expressions.

How it works

To update a Graphic's orientation using expressions:

  1. Create a new GraphicsOverlay.
  2. Create a SimpleRenderer and set expressions on its scene properties: Renderer.getSceneProperties().setHeadingExpression("HEADING"). Then set the renderer to the graphics overlay with GraphicsOverlay.setRenderer(renderer).
  3. Create a graphic and add it to the graphics overlay.
  4. To update the graphic's rotation, use Graphic.getAttributes.put("HEADING", heading)where the attribute key is the expression and the value is the rotation angle.
