Disk No: 1926 Disk Title: Graph By Hoyer PC-SIG Version: S1 Program Title: Graph By Hoyer Author Version: 01/13 Author Registration: $20.00 Special Requirements: Fortran 77 Compiler. This collection of FORTRAN subroutines will make it simple for you to plot high quality scientific and engineering graphs on dot matrix printers which have the ability to print graphics. These subroutines can easily be incorporated into any FORTRAN program, so that your own programs can automatically print high resolution graphs as part of the program output. Also included is a sample program to illustrate the use of the subroutines. This sample program works as a stand-alone graph plotter for plotting graphs from a data file. As an alternative to incorporating the graph plotting subroutines into your own programs, you could instead get your program to write a data file to disk for later plotting using the sample program supplied. Features include resolution options, vertical or horizontal plotting, linear or logarithmic axes, labelling of axes, overlaying grid lines on the graph, joining points with straight lines or a cubic spline, plotting user-defined functions, passing a list of parameters to the user-defined functions, and placing text on the graph.
