All Known Implementing Classes:

SimpleParallel

public interface ProjectionParallel
extends Projection

Projection to parallel coordinates that allows reordering and inversion of axes. Note: when using this projection, pay attention to the two different schemes of dimension numbering: by input dimension and by axis position.
