Both the ChorpboxAnchor and the EllipseAnchor will display the connections
overlaped.Should I write a new Anchor by myslfe?

Thanks.

I guess you could write your own Anchors, but another option is to change
the router a bit. It could detect that a particular row or column has been
occupied already and choose a different row or column, the Chopbox and
Ellipse Anchors will automatically return different locations on the side
of the figure.

Have a look at how the ManhattanConnectectionRouter for ideas.

Best,
Brian.

Use the FanRouter. It will fan out overlapping connections. You can invoke
setSeparation() to specify the distance by which you want the connections to
be spread out. Whatever router you're using currently, should be set as the
next router on the FanRouter. Then, when you set the FanRouter as the
router for your layer, it will use "the next router" for laying out the
connections, and will fan out ones that are over-lapping.

Look at EDiagram example's DiagramEditPart#refreshVisuals().

frouter.setSeparation(50);
frouter.setNextRouter(new BendpointConnectionRouter());
connection.setConnectionRouter(frouter);
connection.add(label,new
ConnectionLocator(connection,ConnectionLocator.MIDDLE));

return connection;
}
The connections are still displayed overlapped.
What's wrong?Is there any constraint with my EditPart?

3.0 had problems if you were using different instance of ChopBoxAnchors at
the ends of the connections. This is fixed in the latest code. If this is
your problem, reuse the same anchor instance at your nodes.

You should be setting the connection router on the connection layer (and
only once), not on the connection itself. Like I said, look at ediagram
example's DiagramEditPart if you need more details.

You mean use the same ChopboxAnchor at the ends of the same connection?
I did that but it still doesn't work.
