Class PolygonalChain
JXG.GeometryElement
↳ JXG.Polygon
↳ PolygonalChain
A polygonal chain is a connected series of line segments determined by
- a list of points or
- a list of coordinate arrays or
- a function returning a list of coordinate arrays.
Defined in: polygon.js.
Extends JXG.Polygon.

Class Detail
PolygonalChain(vertices)
- Parameters:
- {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 polygonal 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}});
