A detailed introduction describes the basic principles. The various commands of each menu are then reviewed with a description of each of the dialog boxes. At the end of the manual several examples of graph construction are given. GraphMu can be used independently of any multivariate data analysis method. The MacMul program facilitates the carrying out of basic analyses (principal component analysis (PCA), correspondence analysis (CA) and multiple correspondence analysis (MCA)) and supplies files which are directly compatible with GraphMu. ADECO (Analysis of Ecological Data) is a complete system based on HyperCard and Microsoft QuickBasic, with developed analysis methods, and also provides files which are compatible with GraphMu. MacMul and GraphMu are available from the author. ADECO is available from: D. Chessel Laboratoire d'Ecologie des Eaux Douces Université Lyon 1 69622 Villeurbanne Cedex. I should like to mention here the importance of the work of Y. Auda in the field of graphical display in data analysis and in particular his thesis, which is the origin of the development of GraphMu (Y. Auda, 1983. Rôle des méthodes graphiques en analyse des données: application au dépouillement des enquetes écologiques. 3rd cycle thesis, Lyon 1 University, 127 p.). Publication of results obtained with this software in scientific reviews is submitted to citation of one of the following papers: Thioulouse J. (1989).
