Questions tagged [legend]

A graph legend is commonly used when plotting several sets of data within the same diagram. The legend associates each plot with its corresponding data.

A legend attached to a graph (or other visualization of data) is used to explain the graphical language (colors, symbols, lines, etc) of the specific visualization.

In scientific software for statistical computing and graphics and also , function legend adds a legend box to an existing plot.
