Abstract
A multi-variate data set is displayed in a plurality of multi-dimensional presentations on a computer having a graphical interface and a keyboard input. The data set includes a plurality of independent variables and, for each independent variable, a plurality of dependent variables. A computer displays the data set in parallel coordinate form on the graphical interface so that each dependent variable of the data set is presented as a series of values along an axis, plural axes arranged in parallel. The graphical interface provides a polygonal line which connects a value on each parallel axis and illustrates a relationship between an independent variable and the dependent variables appearing on each axis. The user input enables a user to superimpose on the graphical interface graphical delimiters either on or between two succeeding parallel axes. The graphical delimiters identify a data subset that includes at least one independent variable and adjacent dependent variables. In response to placement of the graphical delimiters, the computer modifies a presentation of any polygonal lines connecting the adjacent dependent variables and which lies between the graphical delimiters, and d…
