Element Cardinalspline

JXG.GeometryElement
   ↳ JXG.Curve
         ↳ Cardinalspline

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

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

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

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

Reference to the board the cardinal spline is drawn on.


{Array} parents

Array with three entries.

First entry: Array of points the spline interpolates. This can be

  • an array of JXGGraph 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.

Second entry: tau number or function

Third entry: type string containing 'uniform' (default) or 'centripetal'.



{Object} attributes

Define color, width, ... of the cardinal spline


Returns:
{JXG.Curve} Returns reference to an object of type JXG.Curve.
See:
JXG.Curve
Attribute Detail
{Boolean} createPoints
Controls if the data points of the cardinal spline when given as arrays should be converted into JXG.Points.
Defined in: options.js.
See:
Cardinalspline#points
Default Value:
true

isArrayOfCoordinates
If set to true, the supplied coordinates are interpreted as [[x_0, y_0], [x_1, y_1], p, ...]. Otherwise, if the data consists of two arrays of equal length, it is interpreted as [[x_o x_1, ..., x_n], [y_0, y_1, ..., y_n]]
Defined in: options.js.
Default Value:
false

{Object} points
Attributes for the points generated by Cardinalspline in cases createPoints is set to true
Defined in: options.js.
See:
Cardinalspline#createPoints
