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, 3.0]);
var pol = board.create('polygon', [p1, p2, p3, p4]);
