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.
Explanation of parameters:
Executable-- the path to the executable, if not on the system pathAdditionalOptions-- additional options to supply to thedotexecutableImageExtension-- comma-separated list of image extensions to offer in the save dialogDebug-- whether to output debugging informationCleanUpTempFiles-- whether to clean up temporary filesDialogWidth-- the default width of the dialog displaying the graphDialogHeight-- the default height of the dialog displaying the graph
- 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)
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).
