From Partition Method, for Categorical Responses:

The Y axis of the plot is divided into sections corresponding to the predicted probabilities of the response levels for each leaf. The predicted probabilities always sum to one across the response levels. If Display Options > Show Points is selected:

‒Points are distributed evenly and randomly in the horizontal direction.

‒In the vertical direction, they are distributed randomly within the box for their category.
