Class Detail
Locus(p)
The locus element is used to visualize the curve a given point describes.
// This examples needs JXG.Server up and running, otherwise it won't work. p1 = board.create('point', [0, 0]); p2 = board.create('point', [6, -1]); c1 = board.create('circle', [p1, 2]); c2 = board.create('circle', [p2, 1.5]); g1 = board.create('glider', [6, 3, c1]); c3 = board.create('circle', [g1, 4]); g2 = board.create('intersection', [c2,c3,0]); m1 = board.create('midpoint', [g1,g2]); loc = board.create('locus', [m1], {strokeColor: 'red'});
- Parameters:
- {JXG.Point} p
- The constructed curve is the geometric locus of the given point.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
