Hi, PolylineConnection connect the center of an image to the center of another image.

This is my example:

what should I do if I want the connection to be between the lowest part of an image and the top part of another one? (not center to center, but bottom-center to top-center)

Hi,

You'd have to implement your own connection anchor that would allow such
behavior. On the diagram from the screen shot the anchors used are
probably ChopboxAnchor, which set up reference points for the connection
start and end to be the centers of figures that connection links. For your
customized anchors you'd have to provide functionality that will provide
support for making the reference point movable. You can refer to GMF's
BaseSlidableAnchor and its subclasses as examples.
Hope this helps.

Cheers,
Alex
