plottools

 circle
 generate 2-D plot object for a circle
 disk
 generate 2-D plot object for a disk

 Calling Sequence circle(c, r, opts) disk(c, r, opts)

Parameters

 c - list; center of the circle r - (optional) radius of the circle; default is 1 options - (optional) equations of the form option=value. For a complete list, see plot/options.

Options

 • Any applicable 2-D plot option in plot/options can also be given.
 • filled : truefalse
 Specifies whether to fill the inside of the arc. The default is false for circle and true for disk.

Description

 • The rectangle command creates a two-dimensional plot data object, which
 • The circle command creates a two-dimensional plot data object, which when displayed is a circle of radius r centered at c.
 • The disk command creates a two-dimensional plot data object, which when displayed is a disk of radius r centered at c.
 • The plot data object produced by these commands 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.
