Annual ring width data produced by the DIGI-MIC tree ring measurer are transmitted to an APPLE II Plus microcomputer providing the user with an immediate graphical display of the radial growth pattern of the tree. Line graphs of ring widths along radii of a stem cross section and (or) the average for successive stem sections can be compared visually, verified and edited if necessary. Average and individual values are stored on floppy diskettes for further analysis. Computational programs have been written for tabular and graphical display of the complete stem analysis data. Keywords: Annual rings, computer graphics, stem analysis.
