Class Detail
Spline(board, parents, attributes)
- Parameters:
- {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 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
- {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});
