Legend
For an easy interpretation of some Infolayers, use the Legend window.
On the Legend the ILs that belong to the Thematic
, Numeric
or Image
models are represented, and are drawn on the main graphic screen of Spring. Even though it is possible to present ILs on different screens (main or some auxiliar), only one window of "Legend" will be presented, so this window will always be presenting the legends of the active window.
This way, to show this interface, follow the steps described below.
Showing the legend:
-
select on the "Control Panel" the ILs that you want to visualize;
-
click on Show - Legend... . The window "Legend" is presented;
-
click on the triangular button on the left of the IL name to show the legend, or click again to hide it.
The figure below shows an example of legend presentation of a thematic map.

To the right of the name of each IL added to the legend, its Category is shown. The background color is the same background color of the drawing area, that can be defined accessing "Tools - Configure Environment...- SPRING session”.
For Numeric and Image(Band) ILs the quantity of items on the IL legend depends on the settings of the Color Table.
Sorting the elements of the legend
The available options for sorting the elements are:
-
Sort All. The ILs and the legend of each one of these ILs will be sorted alphabetically. Acess the context menu clicking with the right button on the legend header. Select "Sort All" and then one of the options “Increasing” or “Decreasing”;
-
Sort IL. Only the legend of the chosen IL will be sorted alphabetically. The position of the IL on the legend tree remains unchanged. Acess the context menu clicking with the right button on the legend header. Select "Sort IL" and then one of the options “Increasing” or “Decreasing”;
-
Initial Sorting. Returns all the legend items to the initial position, suggested by Spring. Acess the context menu clicking with the right button on the legend header and then select the option “Initial Sorting”;
-
Drag/Drop. Another way to sort the items is to perform the process manually. Just choose one element of the legend (the name or an item of one IL), drag it, move it and drop it on the new position.
