Class Detail
Cardinalspline(board, parents, attributes)
- Parameters:
- {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
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

{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.

- 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]]
