I am generating some figures. I need to arrange them in a proper way (i.e
they should not be overlap with each other). Is there any way to do it
simply or I need to write an algoritham to display all figures one after
other?

Please suggest me.

Thank you

Pavan kumar gupta.

The GEF has an automatic layouter, see for example the flow example
(org.eclipse.gef.examples.flow.parts.GraphLayoutManager).

I am using xylayout. My diagram is an ER-Diagram. I am unable to follow
flow example for my problem. because figures are not in fixed size.

I don't understand the problem. You just need specify each node's current
current width and height, add the edges and then visit the layout with the
graph. Then copy everything back into the actual diagram.
