GRAFFER ======= Graffer is an interactive tool for generating plots of data and/or functions. The original graffer was an IDL program. This version provides most of the same functionality in a Fortran program using gtk-fortran and plplot for the GUI and plotting respectively. To display functions gdl (gnudatalanguage) or IDL is required. As well as the main Fortran program, a number of gdl/idl procedures are included that allow the programmatic generation of graffer plot files.
