Graphviz Plugin

I am running Confluence 2.5.4 and installed Graphviz software. But when I type in

{flowchart}
test->testing
{flowchart}

It shows
flowchart: No useable executable name defined in graphviz.properties

Am I missing something?

Hi,

 Is there documentation available on the other macros shown for this  plugin (diagraph, graph..). Graphviz documentation is general on DOT. I am looking for the macro usage (parameters) document.

TIA,

Spart

I have installed the plugin and graphviz. I am able to run graphviz from the command line, so it correct installation can be confirmed. When i add the flowchart tag to my page I get the following error.

Renderer type: "png" not recognized. Use one of: canon cmap cmapx cmapx_np dia dot fig hpgl imap imap_np ismap mif mp pcl pic plain plain-ext ps ps2 svg svgz vml vmlz vtx xdot

Hello
I have a problem with the path to the created picture:

1. we have set the context of the war to /conflu/clusterB
2. we have set the server base url to http://.../conflu/clusterB
3. no created picture will be shown, the path contains .../clusterb/...

I'm on Red Hat Enterprise Linux 4.5

I am getting the:

Renderer type: "png" not recognized. Use one of: canon cmap cmapx cmapx_np dia dot fig hpgl imap imap_np ismap mif mp pcl pic plain plain-ext ps ps2 svg svgz vml vmlz vtx xdot
 error.  I installed the very latest graphviz from sources.  I have all the extra packages as if it were from RPM. 

 It is still not working for me - can Bob Swift or someone else point me in the right direction?

Thanks!

Graphviz is coded to produce png images. Some Linux installations do not have png image support installed. Try installing libpng on your Linux server.
(updated link to rpms).

And follow Jim's advice from above:
On Linux, you must install the graphviz.rpm, the graphviz-graphs.rpm, and the graphviz-gd.rpm packages

Any tips for OSX on Powerpc installation.
GraphVIZ 2.14.1 from http://www.ryandesign.com/graphviz/

I get the following error:

How do I make successful using by Graphviz plugin with Confluence in Korean(Hangule)
I can't recognize syntax error in this error messages,
please check and fix it.

Great plugin! Thanks Bob. (Solaris 8, JBoss, Confluence 2.7.1)

Correct me if I am wrong.

My problem I believe is similar as others before me.

I create a Graphviz image. Within Ubuntu, I then right click the Graphviz generated image in a Mozilla browser and save image to the 'Desktop'.
I then try to open the generated image in the same browser, it fails and displays the following message:

The image "*test.png" cannot be displayed, because it contains errors.

I can save other png files not generated by Graphviz and view them later with no problems.

One of the previous comments was to:

re-compile GraphViz, with the configure line as such:

./configure --prefix=/usr/local --with-pngincludedir=/usr/local/include/libpng12 --with-pnglibdir=/usr/local/lib

Is this the correct action for my problem?

Thanks

Hi Bob,

We've been running the GraphViz plugin version 1.1.0 under Confluence 2.7.3 for quite some time now without problems.

Recently the plugin started intermittently reporting dot cannot be found errors. This was some weeks ago and at the time I checked this page and checked everything I could think of on the server, tried making the .properties file change, etc. but it didn't help and I wouldn't expect it to - graphviz was still intermittently working fine, and had been working fine for ages with no changes on the server.

Yesterday I finally had the chance to do load testing on the server to see if that affects the plugin. Sure enough, as soon as a high load is placed on the server (in this case 100 fake users each requesting the index of a randomly chosen space and then sleeping between 1 and 60 seconds, again chosen at random) the graphviz plugin started reporting dot not found errors.

I took a look at the source code and discovered that the dot not found error is reported and passes on the actual IOException, but that I don't know where this "ioe" exception data can be seen. I tried to build the plugin from sources (from http://svn.atlassian.com/svn/public/contrib/confluence/graphviz-plugin/trunk) to see if I could debug it but ran into problems at this error:

confluence\extra\graphviz\SpaceGraphMacro.java:[23,40] package org.randombits.confluence.support does not exist

This error appears to be because RandomBits.org was bought out by CustomWare.net and the plugins / libraries were rehomed. Every page using the graphviz macro failed the same way and the only way to fix it was to restart Confluence.

So, something in the plugin is failing with an IOException, but I don't know how to see what that exception is. The source code I am referring to is in DotRunner.java here:

catch (IOException ioe)
        {
            throw new MacroException("Couldn't run '" + verifiedDotExecutableName + "', make sure it is in your PATH", ioe);
        }

Cheers,

Ximon

I modified the graphviz.properties file to match the installation, then used jar.exe to create a new jar, but now confluence raises errors when I try to load the plugin.  Confluence is installed on Windows, and I'm using a personal license for testing. If anyone has suggestions I would be grateful.

For people running solaris, Graphviz is included in the Solaris 10 Software Companion CD 3/05 (at least). You can also download it from http://www.sun.com/software/solaris/freeware/

I just installed it from 3/05 on a new T1000 and it worked like a charm.
