Element Segment

JXG.GeometryElement
   ↳ JXG.Line
         ↳ Segment

This element is used to provide a constructor for a segment. It's strictly spoken just a wrapper for element Line with Line#straightFirst and Line#straightLast properties set to false. If there is a third variable then the segment has a fixed length (which may be a function, too) determined by the absolute value of that number.

Defined in: line.js.
Extends JXG.Line.

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

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|function} length

The points are adapted - if possible - such that their distance is equal to the absolute value of this number.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
See:
Line
Examples:
// Create a segment 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('segment', [p1, p2]);

				
				
// Create a segment providing two points.
  var p1 = board.create('point', [4.0, 1.0]);
  var p2 = board.create('point', [1.0, 1.0]);
  // AB
  var l1 = board.create('segment', [p1, p2]);
  var p3 = board.create('point', [4.0, 2.0]);
  var p4 = board.create('point', [1.0, 2.0]);
  // CD
  var l2 = board.create('segment', [p3, p4, 3]); // Fixed length
  var p5 = board.create('point', [4.0, 3.0]);
  var p6 = board.create('point', [1.0, 4.0]);
  // EF
  var l3 = board.create('segment', [p5, p6, function(){ return l1.L();} ]); // Fixed, but dependent length
