Filter for drawing undirected graphs
Submitted by Hetasser on Wed, 08/14/2013 - 03:04
hi, I have the following problem : I am trying to generate a graph showing the connexions between processes on my server. here is the result (this one is using sfdp) : as you can see, there is a high concentration of edges around the center. In order to have a graph that is more easy to read, I am trying to set a minimum distance between two nodes, but I can't seem to make it work : I tried using fdp/sfdp and playing with the K instruction, I also tried using neato and playing with the edge len, but I don't see any change would you have any tip I could use ?

I've been laying out some large networks with fdp. The visualizations were great with 2.28, but they look much different in 2.30 (most likely because I optimized the fdp parameters in 2.28). Were there any substantial changes to the layout algorithms between these versions that could account for the changes? All I could find in the release notes was the addition of curved edge routing. Is there a way to turn this feature off and revert to the 2.28 settings?

I'm working on a fuzzy pattern recognition system where, fuzzy relations, are represented by matrices.
We can look at such fuzzy matrices as adjacency matrices for directed graphs.
What I need to do is to draw the digraph related to a particular fuzzy matrix.
Is is possible to do this directly from my C code ?
Thank you in advance.

I've been trying to output sccmap results to a file.
In the documentation it says:
sccmap [-dsv] [ -ooutfile ] [ files ]
Assuming my dot file is named g.dot and the results are to be stored in output.txt, I typed in this following command.
sccmap g.dot -ooutput.txt
This doesn't work. It says it doesn't recognize -o, -u, -t, -p, -. and -x.
So I left a space in between -o and output.txt
sccmap g.dot -o output.txt
then it says unable to find output.txt.

I'm a enthusiastic graphviz user and it generates fantastic graphes for me.
But now I have a problem. I have a very great dot-file automatic generated by a script with 13000 lines. This should be visualized with fdp, but I get an error described in
The status of the bug is fixed, so I don't understand the problem. If I visualize with dot, nano, twopi etc. it's no problem, but it has not the look I want. I need fdp.

Hi, whenever I try to compile the .dot file of a bigger graph (in my case a big UML diagram with clusters), I get the following error:
failed at node 31 fdp: maze.c:313: chkSgraph: Assertion `np->cells' failed. I am using the currently stable version 2.28.0 of graphviz (I can't use the Debian version because it doesn't support orthogonal edges yet, so I had to compile it myself). Does anyone have any idea how I could fix this? Thanks in advance Christopher Guckes

Thank you in advance to anyone that can offer some advice on this issue. I am trying to layout undirected graphs with nodes ranging from 200 to 2000. currently I am using SFTP, but will can change that if that is indeed the problem. I am trying layout my graphs in a "Community Structure". Please see this URL for definition. There is only one diagram on the Wiki page and is exactly what I want. http://en.wikipedia.org/wiki/Community_structure When I try to layout the graphs the different "Communities" get pushed together like Venn diagram.

There is only one diagram on the Wiki page and is exactly what I want. http://en.wikipedia.org/wiki/Community_structure#Hierarchical_clustering When I try to layout the graphs the different "Communities" get pushed together like Venn diagram. The communities overlap and I would like to pull them apart to see there shape. What I've already tried: • Playing with K, Len, Repulsive, Mode, and Overlap properties • Using CCOMPS - but the problem is that it will just return one graph because there is at least one edge between each "Community" Again, any help would be greatly appreciated.

I'm trying to generate a block diagram similar to this: http://i.imgur.com/1or8C.jpg And in my attempts at doing so, I looked into fdp and ran the fdpcluster sample on the site but my generated image looks like this: http://i.imgur.com/03fkU.png Am I doing something wrong and if so how can I fix this?

I have a problem with layout of GV. It is something like this.
- if I don't use a layout option then I don't have enough control on the shapes; for example, a column of cells may become a row of cells, etc.
- if I use LR (say), then the graph does not utilize the real estate of a page (assuming page size is specified)
Is there any suggestion?
