Hi, Could you attach an image showing what you need the diagram to look like?

Hi,

You could use the IconNode class from the IconNodes sample project as a starting point to get that kind of node appearance. You could modify it to draw some labels above images; I'm not sure by what criteria that's done in the image.

If your users will draw such diagrams interactively, you could check the SequenceDiagram example for some ideas how to align nodes and links.

If you need to arrange the diagram automatically - I don't think there's a built-in algorithm coming with the control that will arrange the nodes as in the image. It shouldn't be hard to implement it yourself by looping over node's children and setting their Bounds in a row, while pushing larger branches to the bottom of the diagram and arranging them recursively.

I hope that helps,
Stoyan
