Extends JXG.Line.
This element is used to provide a constructor for a general line. A general line is given by two points. By setting additional properties a line can be used as an arrow and/or axis.
Defined in: Line.js.

Class Detail
Line(point1,point2, c,a,b, f)
// Create a line using point and coordinates/
// The second point will be fixed and invisible.
var p1 = board.create('point', [4.5, 2.0]);
var l1 = board.create('line', [p1, [1.0, 1.0]]);

				
				
// Create a line using three coordinates
var l1 = board.create('line', [1.0, -2.0, 3.0]);

				
				
				
				
					
						
Parameters:
{JXG.Point|array|function_JXG.Point|array|function} 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. It is possible to provide a function returning an array or a point, instead of providing an array or a point.
{Number|function_Number|function_Number|function} c,a,b
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. It is possible to provide three functions returning numbers, too.
{function} f
This function must return an array containing three numbers forming the line's homogeneous coordinates.
Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
