Weka doesn't really have a residuals plot - the "Classifier errors"
plot uses the (absolute) difference between actual and predicted value
to scale the "X" in the plot.

When using the Explorer, you can save the predictions to a file via
"More options -> Output predictions" and then generate that plot your
self in a spreadsheet application.

When using the command-line, use the "-classifications" option. For
more details on that option, see the Javadoc of the Evaluation class
(or use -h to display help for classifier):
https://weka.sourceforge.io/doc.dev/weka/classifiers/Evaluation.html

Cheers, Peter
