         ↳ Polygon

A polygon is an area enclosed by a set of border lines which are determined by

Each two consecutive points of the list define a line.

Defined in: polygon.js.
Extends JXG.Polygon.

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

Possible parent array combinations are:
{Array} vertices

The polygon's vertices. If the first and the last vertex don't match the first one will be added to the array by the creator.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
var p1 = board.create('point', [0.0, 2.0]);
var p2 = board.create('point', [2.0, 1.0]);
var p3 = board.create('point', [4.0, 6.0]);
var p4 = board.create('point', [1.0, 4.0]);

var pol = board.create('polygon', [p1, p2, p3, p4]);

				
				
var p = [[0.0, 2.0], [2.0, 1.0], [4.0, 6.0], [4.0, 6.0], [4.0, 6.0], [1.0, 3.0]];

var pol = board.create('polygon', p, {hasInnerPoints: true});

				
				
  var f1 = function() { return [0.0, 2.0]; },
      f2 = function() { return [2.0, 1.0]; },
      f3 = function() { return [4.0, 6.0]; },
      f4 = function() { return [1.0, 4.0]; },
      cc1 = board.create('polygon', [f1, f2, f3, f4]);
