The Legend widget displays labels and symbols for layers in the map. It supports dynamic, tiled, image, feature, and KML layer types as well as WMS layers with an associated legend URL. The Legend widget can be set to automatically update when the visibility of a layer or sublayer changes. When no operational layers are rendered in the map, the Legend widget is blank.
The order in which layers appear in the Legend widget corresponds to the layer order in the map. The widget can also be set to respect the scale dependencies of the layers in the map. This can be a useful indicator to map readers that additional data layers are present in the map but currently not displayed in the map because of scale dependencies.
