3.5. The Legend

The Legend provides an overview of the layers in the map. Layers that appear higher in the legend will appear ``closer'' to the user. If a layer supports classification (currently, only shape layers have this feature) then the classification groups will be shown below each layer. The properties for each group are also displayed with a small graphic. Polygon layers appear as rectangles, lines appear as curved lines, and points appear as circles.

Along the top of the legend is a toolbar which allows quick access to some of the layer manipulation options under Map.

The most used layer related actions are also available from a popup menu. It is raised when a layer is clicked with the right mouse button.

Along the bottom of the legend is the scalebar. The scalebar will be available if there are any layers and the map has a projection set.
