Abstract

We present an information visualisation tool, The Cube, as a solution to the problem of visualising cases derived from large amounts of clinical data. The Cube is based on the idea of dynamic 3D parallel diagrams, an idea similar to the notion of 3D parallel coordinate plots. The Cube was developed to provide interactive visualisation of the case base in terms of relationships between and within cases, in order to enhance the clinician's ability to intelligibly analyse existing patient material and to allow for pattern recognition and statistical analysis.The design and use of The Cube are presented and discussed. We show how the declarative model used and the tight coupling between different visualisation tools directly led to a similarity assessment-based solution to the problem of finding a proper arrangement of dimensions in 3D parallel coordinate displays. The declarative, user-centered nature of The Cube makes it suitable for interactive case-based reasoning (CBR) and opens up for the possibility of case-based visualisation for CBR.
