Edge length (radial/ballon layout)

[andrew lau]

Can I change the length of ballon layout?
I want each edge have different length according to its weight value.
I am just wondering if it is possible to do the following thing in radial layout:

If possible, can anyone tell me the idea of how to start working on it? thanks.

I tried to modify the balloon layout like the following and it does't work:

GraphBalloonLayout<myNode,myEdge> radialLayout;
Point2D pn=new Point2D.Double(500+500*(length)*Math.sin(360*i/numNode*Math.PI/180), 500-500*(length)*Math.cos(360*i/numNode*Math.PI/180));
radialLayout.setLocation(node, pn);

I have no ideas how to fix
