Add image as background of graph

[phanthomas]

To support the insertion of nodes, I'd like to add an image behind an existing graph (or a new one). The picture is supposed to be a groundplan of a building, the nodes its rooms.
I added a photoshopped picture to this post, so you can imagine it.

Is the insertion of the image possible? And if yes, how?

Hi,
This is not currently possible. You could find a hack where a wall is drawn as two nodes, and an edge between them. Several walls form a building...
That's how I drew the map of countries plugin, which effectively provides country maps as backgrounds to networks: https://marketplace.gephi.org/plugin/maps-of-countries/

Best,

Clement

Thanks for your answer.

This is how I currently do it. But it is a bit unfunctional while reordering the "room nodes" with layouts because the edge nodes will be moved as well.

[seinecle]

you can "fix" (or "settle", "pin") the nodes? Do that programmatically, or right click on the node and click "settle". Then, they won't be affected by layouts.

Best,

Clement

That sounds perfect.
Just tried to fix them in the code when creating them and they don't move any more!

Thanks a lot!
