Two equal-area projection techniques (point diagrams and contoured density diagrams) are presented for use in analyzing three-dimensional leaf orientation data. The diagrams display both azimuths and inclinations simultaneously, and allow a rapid visual evaluation of the data. Leaf orientation measurements from three specimens of Nerium oleander are used to illustrate the techniques.In addition, the point diagram permits the grouping of data from a particular canopy layer into regions, simultaneously considering both azimuths and inclinations as well as leaf area. The contoured density diagram allows these regions to be selected on the basis of the actual distribution of leaf area.
