This chapter explains possible error messages, especially these from the Mediawiki integration.
Explanation follows here.
The graph code you did write is invalid, or the parser did not understand it.
Usually this means you made a typo in an attribute name, forgot a closing ]
or similiar mistakes.
If the code you wrote is correct, but the parser still does not parse it properly,
please file a bugreport.
If you are unsure what attributes you can use and what their format is, have a look at the attribute definitions.
graphcnv
understands the following output formats:
To what exact format the graphviz
format is rendered is
set in the config file graph.cfg
. The user cannot
change this from inside the graph code. This means that all
files generated via graphviz are in the same format, f.i. png
.
graphcnv
could not write the file. Please make sure
that the output directory is properly configured in
To create png graphics, the graphcnv
program uses dot
or any other graphviz program like neato
or circo
.
Which program is uses exactly is defined in the config file graph.cfg
.
You need to install the graphviz package, and the program to be used must be
in your path, like /usr/bin/dot
or /usr/local/bin/dot
.
The layouter in Graph::Easy sometimes cannot complete the layout. To prevent it getting
stuck in an endless loop, there is a hard time limit of 5 seconds, after that the
layout stage will be aborted.
If the server is under heavy load, the conversion of the graph might be aborted
even though the layouter would have been able to complete the layout. In this
case, you might try again.
If the layout still does not finish, try as output format graphviz
.
In addition,
please file a bugreport
so that I can improve my code.
Graph::Easy can handle small to medium sized graphs, but on more complicated graphs it has problems like missing edges, nodes or that the layout takes quite a bit of time.
If you have questions, feel free to send me an email (Gnupg key). Bugreports should go to rt.cpan.org.
