Abstract: Abstract Data analysts perform a wide variety of computational tasks in the course of an analysis, and they should be able to do them all on the same platform. Xgobi helps to make this possible by bringing state-of-the-art dynamic graphic methods for the display and manipulation of scatter plots to the UNIX®workstation, and linking them to the S data analysis environment. Xgobi is implemented in the X Window System™, which offers portability across a wide variety of workstations, X terminals, and personal computers, as well as the ability to run smoothly across a network. A user can run xgobi and S simultaneously, making it possible to use each program’s functions on the same data. Using a highly interactive direct-manipulation design, xgobi offers an array of familiar scatterplot tools. Users can view pairwise plots, three-dimensional rotations and grand tour sequences. Views of the data can be reshaped, and points can be identified or brushed. Projection coefficients and brushing characteristics can be saved in a format usable by S, or in ASCII files. A user can run two or more independent xgobi processes and pass data between them. Xgobi also includes an extensive on-line help facility.
