Element Ellipse

JXG.GeometryElement
   ↳ JXG.Curve
      ↳ Conic
            ↳ Ellipse

This element is used to provide a constructor for an ellipse. An ellipse is given by two points (the foci) and a third point on the the ellipse or the length of the major axis.

Defined in: conic.js.
Extends Conic.

Element Detail
Ellipse
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "ellipse".

Possible parent array combinations are:
{JXG.Point|array} point1
{JXG.Point|array} point2
{JXG.Point|array} point3

Parent elements can be three elements either of type JXG.Point or array of numbers describing the coordinates of a point. In the latter case the point will be constructed automatically as a fixed invisible point.


{JXG.Point|array} point1
{JXG.Point|array} point2
{number|function} number

Parent elements can be two elements either of type JXG.Point or array of numbers describing the coordinates of a point. The third parameter is a number/function which defines the length of the major axis Optional parameters four and five are numbers which define the curve length (e.g. start/end). Default values are -pi and pi.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create an Ellipse by three points
var A = board.create('point', [-1,4]);
var B = board.create('point', [-1,-4]);
var C = board.create('point', [1,1]);
var el = board.create('ellipse',[A,B,C]);
