Is there a way to have boxes show up horizontally in some cases, and vertically in others? (see related question).
Here is the code and output which I am getting:
code:
/**

digraph G {
graph [
rankdir = "TB"
];

Output:
Obviously this is far too long. What I want is to move each synapse into its own line (I think it's called a 'rank' in Graphviz-jargon). Apparently, there is no way to do this, but there is a trick. Therefore, I take the same code above and introduce invisible edges like so
code:

rankdir = "TB"

label = "Simulator Engine";
/**

subgraph cluster_T1_N3 {

label = "Neuron n";

"T1_N3_S3" [

"T2_N1_S2" -> "T2_N1_S3" [style=invis];
}
label = "Topology 2";
}
}
}
and the output now looks more appealing.
output:
But now there is a huge gap between the synapse boxes. Setting nodesep=0.1 or len=0.1 has no effect. Can anyone tell me how to fix this, or how to redesign this.
NOTE: If anyone is curious why I go from 1 to 2 to n, it is because I plan to put an ellipses in there, but I have no clue how to do that...cross that bridge when I get to it.

It's ranksep you're looking for - add this line to the attributes for the graph:
ranksep = 0.1
In dot, this gives the desired rank separation, in inches. This is the minimum vertical distance between the bottom of the nodes in one rank and the tops of nodes in the next.
