<legend> Legend

A list or table of the explanations for symbols, characters, terms, or abbreviations, where each entry in the list names a symbol (or similar) and provides a gloss for that symbol. Such lists act as a key to the symbology of a graphic, figure, or table.

Usage/Remarks

Legends typically accompany figures or tables to act as a key to the symbols, characters, or abbreviations used in the graphic, figure, table, etc. Such lists may show a heading such as “Key” (“Légende” in French, “Legende” in German). Legends may also be called “where lists”, “keys”, “variable lists”, “legends”, “symbol charts”, etc., with the exact list heading given as the <title> of the <legend> element.
