Bug reported on https://forum.gephi.org/viewtopic.php?t=1832&p=6281#p6281

Way to reproduce:

  • Start Gephi and open the Java example
  • Switch to Data Labratory and select all nodes (CTRL + A)
  • Right click and choose "Edit nodes"
  • Set x-, y- and z-coordinate to 0
  • Switch to Overview and run ForceAtlas 2
    -> all Nodes disappear (and have x- and y-coordinate set to NaN).

Doing the same thing and setting x- and y- coordinate to 1, everything works as desired.

This is happening because all nodes are located in the same point and therefore messes up the distance calculation in layouts.

But this does not happen, if (x,y,z) = (1,1,1) is set - only when setting everything to 0!
Looks like the gephi streaming plugin is adding nodes initally to (0,0,0) - therefore ForceAtlas 2 is unusable with streaming :-/
