Class Detail
Arrow(point1,point2, a,b,c)
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_Number_Number} a,b,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]);
