Re: Calculate weight by number of parallel edges?

Thank you. I believe my question may not have been as clearly articulated as I had hoped. Perhaps a little more detail on my project will make sense.

I am working on a dynamic network visualization and would like to see the edges grow as well as the nodes. The columns in my actual data file are:
(Source, Target, Type, Id, Label, Interval, Weight, firstDate, secondDate, otherVar, and otherVar2). I believe I am getting multiple edges between the same nodes because the variables are different. For my dynamic visualization, however, I would like to combine the weights between the same source and targets regardless of the values of other variables. Is this possible?

If the weight is only 1 for each edges :
Having this file

CODE:

A;BA;CB;CB;CB;C

And just File >> Open on Gephi will do the job

If you have a weight that can be different than 1, I think it's not possible to do it in CSV. Then create a gdf file like this

CODE:

nodedef>name VARCHARABCedgedef>node1 VARCHAR,node2 VARCHAR,weight DOUBLEA,B,1A,B,5A,C,1B,C,1B,C,1B,C,1

And File >> Open do the job correctly

Calculate weight by number of parallel edges?

2016-06-14T16:43:56+01:00

Hello,

I am trying to calculate an edge weight based on the number of parallel edges between nodes. For example, my data include:

source, dest, weight
A, B, 1
A, C, 1
B, C, 1
B, C, 1
B, C, 1

In the above example, I would like to display the data as:
A, B, 1
A, C, 1
B, C, 3

Is there a way to do this? I am using the streaming plugin from an OrientDB database.

Thank you
