graphviz-treevisualize-weka-package

TreeVisualize plugin for the Explorer using GraphViz (http://www.graphviz.org/) to generate the tree.

By default, the plugin expects the dot executable to be available on the system path. If that should not be the case, you can specify the correct location in the GraphVizTreeVisualization.props properties file.

Simply create the following file:

Linux/Mac

$HOME/wekafiles/props/GraphVizTreeVisualization.props

Windows

%USERPROFILE%\wekafiles\props\GraphVizTreeVisualization.props

And add the following content (adjust path, of course):

Linux/Mac
```
Executable=/some/where/dot
```

Windows

Executable=C:/Progam Files/some/where/dot.exe

Additional options for the executable can be specified with the AdditionalOptions property in the same properties file.

GraphVizTreeVisualization.props

Explanation of parameters:

Executable -- the path to the executable, if not on the system path
AdditionalOptions -- additional options to supply to the dot executable
ImageExtension -- comma-separated list of image extensions to offer in the save dialog
Debug -- whether to output debugging information
CleanUpTempFiles -- whether to clean up temporary files
DialogWidth -- the default width of the dialog displaying the graph
DialogHeight -- the default height of the dialog displaying the graph

Releases

2022.4.13 (Weka >= 3.9.1, Weka >= 3.8.1)
2018.5.13 (Weka >= 3.9.1, Weka >= 3.8.1)
2017.3.3 (Weka >= 3.9.1)
2014.8.1 (Weka >= 3.7.11 and < 3.8.1 and < 3.9.1)

Troubleshooting

You can use the 2014.8.1 release with Weka 3.8.1 or 3.9.1, but you need to create the GraphVizTreeVisualization.props properties file in the location explained above and add the following parameter to it (you may also have to add the Executable parameter):

AdditionalOptions=-Tpng

The new class loading mechanism in these Weka releases prevents the properties file from being loaded and graphviz not getting an output type parameter in its command-line, resulting in outputting the graph data again (which of course will fail to load as an image, see issue #3).
