Class Segment
Extends
JXG.Line.
This element is used to provide a constructor for a segment.
It's strictly spoken just a wrapper for element Line with JXG.Line#straightFirst
and JXG.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).
Defined in: Line.js.

Class Detail
Segment(point1,, length)
// 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]); 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]); var l2 = board.create('segment', [p3, p4, 3]); var p5 = board.create('point', [4.0, 3.0]); var p6 = board.create('point', [1.0, 4.0]); var l3 = board.create('segment', [p5, p6, function(){ return l1.L();} ]);
- Parameters:
- {JXG.Point|array_JXG.Point|array} point1,
- 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
- (optional) The points are adapted - if possible - such that their distance has a this value.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
