There is no evidence of significant differences for models joined by the vertical lines. Depending on the model we are considering, different groups can be formed. The groups are identified using the mean rank of a model ± the critical distance.
There are several plotting options coded for the the nemenyi.m. I have also put an option for changing the colourmap to better visualise the comparisons. A potentially useful option is to set:
