Hi,
Alignment problem for libgv_python.
I used the python script to generate one graph: "test.py"
#!/usr/bin/python
import gv
g = gv.digraph("G")
gv.setv(g, "label", "Just for test")
c1 = "cluster1"
gv.graph(g, c1)
g1 = gv.findsubg(g, c1)
gv.setv(g1, "label", c1)
gv.node(g1, "a1")
gv.node(g1, "a2")
gv.node(g1, "a3")
gv.edge(g1, "a1", "a2")
I used graphviz for an academic paper of a field that usually doesn't use visualization techniques.
I was asked by the journal editor to properly cite graphviz in the references with the author and year in addition to organization and URL. Does anyone knows about this?
Dear All,
I've had occasion to return to the problem discussed here . I eventually got version 2.28 running on my linux shared host at webfaction. The twopi layouts on my mac running 2.29 were still better, but the layouts generated by 2.28 were acceptable. I've returned to this now and thought I could improve matters by installing GV 2.36 on my shared host. To my dismay, I have what looks like a regression.
Hi- I've installed Graphviz from the MSI without admin rights, and have built pygraphviz with python setup.py build -c mingw32 install.
When I try to import pygraphviz, I get the error "No module named _graphviz".
Can someone help? I would really like to use pygraphviz to read .dot files in a portable environment.
Hello,
Newbie here. I built the latest source code from the download page and tried to build the demo code referenced in the Graphviz as a library guide. When I run make, I get "undefined" reference errors for all the graphviz method calls. The loader does not seem to work. I built the code on a debian VM and it worked just fine; but when I try to make the code on Ubuntu 12.04 (both 32-bit and 64-bit) as well as 13.10, I get these loader errors. Here are the exact errors I am getting:
~/Downloads/graphviz-2.36.0/dot.demo$ make
cc `pkg-config libgvc --libs` dot.o -o dot
Hi,
I noticed something very strange with a small graph. It only seems to exist in one certain configuration (that I can find) of said graph. Namely: the direction of one of the edges flips depending on the presence of a label. If the label is present, the edge goes the wrong way, if it is absent, the edge points the right way.
Here are the two versions of the graph:
Correct version:
Incorrect version:
I have received a graph's xml file generated using mxgraph.
I don't have mxgraph installed but have graphviz library. Is it possible to render graph using graphviz?
I've just had an email from a user of a Perl interface to Graphviz.
The author surmises that since the 2.3x versions of Graphviz, installed on Windows, the PATH is not updated to point to the dir containing dot.exe.
Is this the case?
Context: I've been asked by a user of my Perl wrapper - GraphViz2 - around Graphviz, how to force nodes within a subgraph to be placed top-to-bottom, in an order specified by the user. So I looked at the rank attribute, but...
I find this part of the explanation of the rank attribute hard to follow:
If rank="source", all nodes are placed on the minimum rank, and the only nodes on the minimum rank belong to some subgraph whose rank attribute is "source" or "min".
How can it refer to 'all nodes', and also 'the only nodes'?
Hello, I have been using Graphviz for a while with source data from Excel and dot language generated with formulas but never integrated Excel and dot.exe to automate the whole process. I would like to use an external resources if available to do this and even more (such as providing parametrization means).
See pic I want the red node to come closer to the blue node. Can I achieve this? I use {rank=same; "Occlusion"->"Occlusion Ct" } to make the blue and the red to come on the same level in the graph. Thanks! 
Hi,
1. Can I generate .dot file at runtime?
If yes, pls. guide or give sample code or references.
2. If I need to change the background color of node, "filled" property to different color depending on data to be set, is it possible?
In faqs, its saying feature is not available but the library version referred is old. 1.1.x.

gg

I am new to GraphViz and I was trying to set the positions of the node so that I can get my preferred orientation. But I couldn't get any help. Is there any way I can set the co-ordinates of the nodes or any other alternative?
When can I expect new development snapshot *.msi which will fix this assert?
I.e. version > graphviz-2.37.20140325.msi
?
See my bug report @ http://www.graphviz.org/mantisbt/view.php?id=2437
IMO this is easy to fix, as per my experience with C/++ asserts are easily fixed, unless there is a bigger problem in the code.
When I can expect fixed devel snapshot? I tried newest released today, but the same error is displayed.
I'm using the latest OS X Mavericks 10.9.2 update.
I did "brew install graphviz" to install graphviz-2.36.0_1
Then when I run "neato test.dot" it says:
[code]
➜ scratch neato
There is no layout engine support for "neato"
Use one of:
➜ scratch which neato
/usr/local/bin/neato
[/code]
Any help?
Thanks a lot!
sorry everybody, but I don't know that how to run demo.c
I just use visual studio 2013 and link lib, but it don't run: error lnk2001 unresolved external symbol _Agdirected
thanks you so much!
Hi everybody,
i am currently trying to plot a energy flow chart with graphviz.
A pie chart should be proper to describe the energy flow amount, but unfortunately i cannot find this node shape in the built-in liberay, so comes this question.
i've also considered using Record-shaped node to do the job, but is there anyway to define the size of the boxes in the node?
Thanks for your answer in advance!
Regards,
sildea
someone can help me please? I am trying to install nagvis, but looks like that i need to install this program first. Where do i find steps to install this on my solaris, please?
My project is read/ write file .dot use library graphviz, but I don't know how to read file dot and save data from file dot to data structures(save node and edge)
thanks!
