Acomputer system has been developed to process geochemical data. The processed data are plotted onto each of square, cube, triangle and tetrahedron. The result using a square or a triangle is instinctly shown on the computer display. On the contrary, the result using a cube and a tetrahedron is given as a stereoimage pair for the 3-dimensional view. A user can choose interactively a component (or a component assemblage) corresponding to each axis or apex. It is expected that the interactive system gives us many valuable suggestions in the geochemical discussion.
