Abstract
Parallel Coordinates are a powerful method for visualizing
multidimensional data, however, with large data sets they can become cluttered
and difficult to read. On the other hand, a Star Glyph can be used to display
either the attributes of a data item or the values across all items for a
single attribute. Star Glyphs may readily provide a quick impression; however,
since the full data set will require multiple glyphs overall readings are
more difficult. We present an interactive integration of the visual
representations of Parallel Coordinates and Star Glyphs that utilizes the
advantages of both representations to offset the disadvantages they have
separately. We discuss the role of uniform and stepped color scales in the
visual comparison of non-adjacent items and Star Glyphs. Our visualization
provides capabilities for focus-in-context exploration of the data using two
types of lenses, and interactions specific to the 3D space.
