make the location of vertices fixed when adding new edges
Posted: 10 Feb 2014 23:05
Hi,
my question, briefly, is that how could I make the position of vertices 'fixed' in an initial graph in gephi, so when I append and open another subset of edges to the existing graph, the position and location of nodes wont change? is it possible to do in gephi at all? I have two csv file for them.
Just to draw the details: I want to visualize a graph in gephi which consists of two subgraphs. a 20*20 grid graph that I have its edge list as a csv file. and another subgraph that is a set of edges between the 400 nodes in the first grid. I want to have a visualization exactly in form of grid. So, at first I open the grid graph in gephi and layout it, so i have a graceful grid, but when I add another subgraph (a csv file) and I choose it to append on existing grid graph (not a new graph), unfortunately the added edges changes the location of vertices in the grid. So it is not an accurate grid with more number of edge anymore.
P.S in the grid, all vertices are labeled from 0 to 399, so I want to have a grid where in the bottom it has 0 to 19 nodes and it creates a 20*20 grid by the location of these 400 nodes.
Thanks a lot in advance.
