plottools

 arc
 generate an arc of a circle

 Calling Sequence arc(c, r, a..b, options)

Parameters

 c - center of the circle r - radius of the circle a - starting angle (in radians) b - finishing angle (in radians) options - (optional) equations of the form option=value. For a complete list, see plot/options.

Description

 • The arc command creates a two-dimensional plot data object, which when displayed is an arc of the circle of radius r centered at c.  The starting and finishing angles of the arc are specified with the range a..b, respectively.
 • The plot data object produced by the arc command can be used in a PLOT data structure, or displayed using the plots[display] command.
 • Remaining arguments are interpreted as options, which are specified as equations of the form option = value. For more information, see plottools and plot/options.
