Any applicable 2-D plot option in plot/options can also be given.

filled : truefalse

Specifies whether to fill the inside of the ellipse. The default is false.

rotate = real

Specifies that ellipse should be be rotated by the specified angle (in radians). The default is 0.

super = positive real, list of two positive reals, or the value true

The super option given alone is equivalent to super=m (with m=4) which is equivalent to super=[m,m]. More generally ellipse([x0, y0], a, b, super=[m1,m2]) draws the superellipse (or generalized superellipse when $\mathrm{m1}\ne \mathrm{m2}$)

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) draws the ellipse

The super option may be used to draw a superellipse or generalized superellipse.

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.

The super option was introduced in Maple 2019.

The plottools[ellipse] command was updated in Maple 2023.

The rotate option was introduced in Maple 2023.
