Element Detail
Tracecurve
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "tracecurve".
- Possible parent array combinations are:
-
{Point|Point} Parent
- elements of Tracecurve are a glider point and a point whose locus is traced.
- See:
- JXG.Curve
- Examples:
// Create trace curve.
var c1 = board.create('circle',[[0, 0], [2, 0]]),
p1 = board.create('point',[-3, 1]),
g1 = board.create('glider',[2, 1, c1]),
s1 = board.create('segment',[g1, p1]),
p2 = board.create('midpoint',[s1]),
curve = board.create('tracecurve', [g1, p2]);
