Description
|
|
|
•
|
The ellipse command creates a two-dimensional plot data object, which when displayed is an ellipse centered at c with radial distances a and b, that is, ellipse([x0, y0], a, b) graphs the ellipse
|
|
•
|
The plot data object produced by the ellipse 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.

|
|
Ellipse in arbitrary forms can be generated with object transformations like rotate in the plots package.
