[[editinglegends#ModelChoice|Choose the Model]] for which you want to edit the Legend. The displayed graphic parameters are in correspondence with the Spatial Type of the chosen Model.

===== Points =====

When the Spatial Type is a Point, a symbol is used as graphic appearance. Symbols can be vector, text or image-based.

In Orbit, symbols are chosen from a Symbol Library and specifications such as color and size are set. To define symbols, check out the chapter about [[symbols_library|Symbol Libraries]]. Colors are irrelevant for image-based symbols.
