JXG.GeometryElement
↳ JXG.Line
↳ Axis
This element is used to provide a constructor for an axis. It's strictly spoken just a wrapper for element Line with JXG.Line#straightFirst
and JXG.Line#straightLast properties set to true. Additionally JXG.Line#lastArrow is set to true and default Ticks will be created.
Defined in: line.js.

Element Detail
Axis
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "axis".
- 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.
- Examples:
// Create an axis providing two coord pairs.
var l1 = board.create('axis', [[0.0, 1.0], [1.0, 1.3]]);
