Introduction
XmdvTool allows users to examine data sets with a large number of dimensions
or parameters. We refer to this as multivariate data. 4 distinct
methods of projecting this N-dimensional data onto a 2-D screen are provided:
scatterplots, glyphs, parallel coordinates, and dimensional stacking.
Users can switch between display techniques by simply clicking on buttons
in the interface. A major tool in XmdvTool for providing insights
into N-D spatial relations is the N-D brush, which allows users to perform
operations on the data points which fall within a user-specified N-D subspace
of the total space defined by the data.
