Element Detail
Locus
The locus element is used to visualize the curve a given point describes.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "locus".
- Possible parent array combinations are:
-
{JXG.Point} p
- The constructed curve is the geometric locus of the given point.
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
// 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'});
