Abstract
This paper describes a tool being developed to allow users to visualise the ripening characteristics of fruit. These characteristics, such as sugar, acid and moisture content, can be measured using non-destructive Near Infrared Reflectance (NIR) analysis techniques. The four dimensional nature of the NIR data introduces some interesting visualisation problems. The display device only provides two dimensions, making it necessary to design two dimensional methods for representing the data. In order to help the user fully understand the dataset, a graphical display system is created with an interface that provides flexible visualisation tools.
