Element Arrow
JXG.GeometryElement
↳ JXG.Line
↳ Arrow
This element is used to provide a constructor for arrow, which is just a wrapper for element
Line with Line#straightFirst
and Line#straightLast properties set to false and Line#lastArrow set to true.
Defined in: line.js.

Element Detail
Arrow
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "arrow".
- Possible parent array combinations are:
-
{JXG.Point|array} point1
{JXG.Point|array} point2
- Parent elements can be two 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.
-
{Number} a
{Number} b
{Number} c
- A line can also be created providing three numbers. The line is then described by the set of solutions of the equation a*x+b*y+c*z = 0.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- See:
- Line
- Examples:
// Create an arrow providing two points.
var p1 = board.create('point', [4.5, 2.0]);
var p2 = board.create('point', [1.0, 1.0]);
var l1 = board.create('arrow', [p1, p2]);
