On the Use of Parallel Coordinates for Temporal Multivariate Data

This work presents the results from a user centered evaluation of visual representations of temporal multivariate data using 2D and3D parallel coordinates. The objective of the evaluation was to investigate whether 2D or 3D representations increase user performance when the data consists of temporal multivariate data and the visual representation contains interactive user tools. The results show that the 3D parallel coordinates representation outperforms 2D parallel coordinates with regards to both accuracy and response time.This result is of interest to the information visualization community, since it shows the usefulness of visual representations of temporal multivariate data
