Abstract
In this paper, we propose a new dynamic graphical method for multivariate data, Dynamic Scatterplot Matrix. This method is an extension of the scatterplot matrix with rotation. The scatterplot matrix is one of the fundamental graphical methods for multidimensional data, which is all pairwise scatterplots arranged in a rectangular array so that adjacent plots share an axis in common. It is difficult to investigate the relations among more than two variables with the scatterplot matrix. Another graphical method for multidimensional data is rotation. Rotation allows us to explore the joint structure of any three of the variables. But no single low-dimensional view will capture the whole structure that is interesting about multidimensional data. Dynamic scatterplot matrix is developed to overcome the defects of the scatterplot matrix and rotation. We also show the system for Dynamic scatterplot matrix on a UNIX workstation. The system is developed with the language C and X lib.
