hello， everyone， recently I develop a labview program which can drawing network topology tree figure and it connect embed system by TCP/IP， but it worry that I do not know how to drawing above figure and must to use c/c++ language to develop, or can you give me a example or data based on labview platform? thanks

Do you need to interact with the underlying element? I do not see on top of what kind of element you are trying to draw, so just general thoughts

You can place picture (or graph) with transparent background on top of your picture, match coordinates. Then you can draw anything on top picture, images will be "added". But this element on top will get all mouse clicks, interaction with bottom element will be difficult.

PS edit: if your underlying element is .net control, you can not place elements in LabVIEW on top of it. May be you can, but not trivial.
