Windows 7 graphviz not working


Graphviz conversion was working for XP but I upgraded to W7 and now getting the following error:

Warning: syntax error in line 2 near '.3'

The content of the file is:

digraph shockShockS1Callee {
ShockS1 [shape=box,style=filled,.7 .3 1.0]
Timer2_ISR -> ShockS1

Has the command syntax changed for W7?



How to make recursive nodes?

I'm currently writing a graphs library in Java, and I would like a tool to visualize some graphs.

In my model, Graphs are composed of Nodes and Edges. Every Node have a certain number of Ports (I/O/IO) and Edges link those Ports together. Some special nodes are called GraphNodes and embed a Graph. The Ports of these GraphNodes are mapped to some Ports of the internal Nodes.

Nodes of more than one color

Hi there,

We would like to use Dot (and then the subsequent xDot)
to render Glycans in our Pathway Logic tool.

I attach a key for one such variant.

I'd like to know if there is any way to produce
the two color nodes, and stars.

Any suggestions would be great!

Cheers Ian.

Avoid stretching table inside td.

Hello all,

I am generating some graphs that use HTML like labels with nested tables. If the cell that contains a table is bigger than the table's required size (due to other cells in the outer table), then the inner table is stretched to fill the cell. I would like the inner table to only use as much space as it needs, and leave the remainder of the cell empty. Alternatively, I would be happy with the cell being sized independently from other cells in the same column, and only being as wide as the inner table required.

How to go from graphiz to PNG? What am I missing here?

I'm using dot in graphiz to display a directed graph, and I would like to export this to PNG. I am pretty new with this whole process and find it very interesting; however, I cannot figure out for the life of me how to export this to an image file. I see nothing in the GVEdit for Graphviz application to do this.

I installed the executable package from AT&T ( for Windows if that helps.

Can someone point me in the right direction?
