This sample shows how to use the rotation visual variable to visualize the aspect of the terrain of a small island in Alaska.
The rotation visual variable can be set directly in the renderer's constructor.
var rotRenderer = new SimpleRenderer({
symbol: new SimpleMarkerSymbol({
color: "white",
path: "M14.5,29 23.5,0 14.5,9 5.5,0z",
angle: 180,
size: 10
}),
visualVariables: [{
type: "rotation", // indicates that symbols should be rotated based on value in field
field: "grid_code", // field containing aspect values
rotationType: "geographic"
}]
});
