Element Spline

JXG.GeometryElement
   ↳ JXG.Curve
         ↳ Spline

This element is used to provide a constructor for (natural) cubic spline curves. Create a dynamic spline interpolated curve given by sample points p_1 to p_n.

Defined in: curve.js.
Extends JXG.Curve.

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

Possible parent array combinations are:
{JXG.Board} board

Reference to the board the spline is drawn on.


{Array} parents

Array of points the spline interpolates. This can be
  • an array of JSXGraph points
  • an array of coordinate pairs
  • an array of functions returning coordinate pairs
  • an array consisting of an array with x-coordinates and an array of y-coordinates
All individual entries of coordinates arrays may be numbers or functions returning numbers.


{Object} attributes

Define color, width, ... of the spline


Returns:
{JXG.Curve} Returns reference to an object of type JXG.Curve.
See:
JXG.Curve
Examples:
var p = [];
p[0] = board.create('point', [-2,2], {size: 4, face: 'o'});
p[1] = board.create('point', [0,-1], {size: 4, face: 'o'});
p[2] = board.create('point', [2,0], {size: 4, face: 'o'});
p[3] = board.create('point', [4,1], {size: 4, face: 'o'});

var c = board.create('spline', p, {strokeWidth:3});
