By means of Parallel Coordinates pla-nar "graphs" of multivariate relations are obtained. Certain properties of the relationship correspond to the geometrical properties of its graph. On the plane a point +-. line duality with several interesting properties is induced. A new duality between bounded and unbounded convex sets and hstars (a generalization of… (More)

A methodology for <b>visualizing</b> analytic and synthetic geometry in <i>R<sup>N</sup></i> is presented. It is based on a system of <b>parallel coordinates</b> which induces a non-projective mapping between N-Dimensional and 2-Dimensional sets. Hypersurfaces are represented by their planar images which have some geometrical properties analogous to the… (More)

T he display of multivariate datasets in parallel coordinates, transforms the search for relations among the variables into a 2-D pattern recognition problem. This is the basis for the application to Visual Data Mining. The Knowledge Discovery process together with some general guidelines are illustrated on a dataset from the production of a VLSI chip. The… (More)

Automation has arrived to Parallel Coordinates. A geometrically motivated classifier is presented and applied, with both training and testing stages, to 3 real datasets. Our results compared to those from 23 other classifiers have the least error. The algorithm is based on parallel coordinates and : has very low computational complexity in the number of… (More)

With a system of <italic>parallel coordinates</italic>, objects in <italic>R<supscrpt>N</supscrpt></italic> can be represented with planar “<italic>graphs</italic>” (i.e., planar diagrams) for arbitrary <italic>N</italic> [21]. In <italic>R</italic><supscrpt>2</supscrpt>, embedded in the projective plane, parallel coordinates induce a point… (More)
