Graphis is a data-graphing and -analysis program for 2D (one independent variable) and 3D (two independent variables) data. The program contains 15 2D plot types and nine 3D plot types. Curves in 2D and 3D can be plotted with Cartesian, polar, or parametric coordinates. New features in version 2.0 include plotting of statistical functions, statistical analysis plots, nonlinear regression, a color-map editor, and many new 3D surface-plotting features. For example, surfaces can be color-mapped, texture-mapped, or transparent, and they can display contours and have up to eight translate/rotate/scale operations applied.
