link.vertex(index)
Return the vertex at index
.
link.vertex(index, vertex [, opt])
Update the vertex at index
with value of vertex
. By default the new value is merged into the old value. Pass the { rewrite: true }
option along to disregard the old value.
A vertex has only two properties, x
and y
. It may be defined as a g.Point object.
Example vertex:
link.vertex(0, {
x: 100,
y: 200
});
Note that all vertices are stored in an array on the link model under the attribute vertices
. Use the link.vertices
function to access the array.
