Abstract

This paper introduces a number of refinements to theParallel Coordinates visualisation metaphor for multi-dimensionaldata. Firstly, the traditional set of poly-linesare replaced with a collection of smooth curves across theattribute axes, allowing individual data elements to betraced under certain limitations; normally impossible dueto the crossing problem'. Then the notion of spreadingout points on axes with a few discrete values isintroduced, which leads onto a simple focus+contexttechnique when the user selects values on such axes.
