How To Change Colors, Based on Edge Direction?

[Rodger22]

Dear Experts,

I have a small Neo4j graph with parents and children that I've imported into Gephi.

parent -> child -> grandchild


So far, all the edges are directional,
one direction only, PARENT_OF.


Given a single child node,
is there a way to set the edges to different colors?

One color for the parents.
One color for the grandchildren.

If so, what is the secret?


Thanks a lot!

Hi,

Interesting. I personally don't see a way to do that directly from the Gephi GUI. That will involve data wrangling, but you can do specify an edge color directly in the network file describing your graph. The gexf format (primer: http://gexf.net/1.2draft/gexf-12draft-primer.pdf) provides a color attribute for edges:

Code: Select all

<edge ... >
   <viz:color r="157" g="213" b="78"/>
</edge>

Best,

Clement

Thanks for responding. No wonder I couldn't figure it out.

Perhaps the Gephi team can add this feature to an upcoming version.

I'm thinking similar to an Excel macro.
If <0 -> color of cell is red.

In Gephi,

If direction->, color of edge is blue
If <-direction, color is green

Elseif no direction, color is red

Make sense?
