SciFigs: Legend

A legend

A legend is a graphical object that can be inserted in a graphic sheet. A legend is a description of various line, symbol and text attributes used for plotting curves on a Graph containing line layers.

Create a legend

In a graphic sheet such as figue, select the menu Insert/Legend. Alternatively, use the legend toolbar icon or right-click on a blank part of the graphic sheet and access Insert/Legend through the context menu (useful for Mac users who have no top menu bar when the graphic sheet is embedded in a larger application, e.g. inside geopsy).

A small box with Title' inside appears in the Graphic Sheet.
