Element PolygonalChain

JXG.GeometryElement
   ↳ JXG.Polygon
         ↳ PolygonalChain

A polygonal chain is a connected series of line segments determined by

Each two consecutive points of the list define a line. In JSXGraph, a polygonal chain is simply realized as polygon without the last - closing - point. This may lead to unexpected results. Polygonal chains can be distinguished from polygons by the attribute 'elType' which is 'polygonalchain' for the first and 'polygon' for the latter.

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

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

Possible parent array combinations are:
{Array} vertices

The polygon's vertices. Additionally, a polygonal chain can be created by providing a polygonal chain and a transformation (or an array of transformations). The result is a polygonal chain which is the transformation of the supplied polygona chain.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
    var attr = {
            snapToGrid: true
        },
        p = [];

	p.push(board.create('point', [-4, 0], attr));
	p.push(board.create('point', [-1, -3], attr));
	p.push(board.create('point', [0, 2], attr));
	p.push(board.create('point', [2, 1], attr));
	p.push(board.create('point', [4, -2], attr));

 var chain = board.create('polygonalchain', p, {borders: {strokeWidth: 3}});
