Multivariatedata sets exist in a wide variety of fields andparallel coordinates visualizations are commonly used for analysing such data.This paper presents a usability evaluation where we compare threetypes of parallel coordinates visualization for exploratory analysis of multivariatedata. We use a standard parallel coordinates display with manualpermutation of axes, a standard parallel coordinates display with automaticpermutation of axes, and a multi-relational 3D parallel coordinates displaywith manual permutation of axes. We investigate whether a 3Dlayout showing more relations simultaneously, but distorted by perspective effects,is advantageous when compared with a standard 2D layout. Theevaluation is accomplished by means of an experiment comparing performancedifferences for a class of task known to be well-supportedby parallel coordinates. Two levels of difficulty of the taskare used and both require the user to find relationshipsbetween variables in a multivariate data set. Our results showthat for the manual exploration of a complex interrelated multivariatedata set, the user performance with multi-relational 3D parallel coordinatesis significantly faster. In simpler tasks, however, the difference isnegligible. The study adds to the body of work examiningthe utility of 3D representations and what properties of structurein 3D space can be successfully used in 3D representationsof multivariate data.
