GPLOT can be used to plot variables from inside any Fortran program. This subroutine is not intended to replace other graphics packages, or plotx, but to rather allow the user to look at arrays of data in the middle of fortran codes. XYPLOT is also not intended to replace plotxy, but to work as a user-friendly interactive program, in which plots of data files can be created from the command line. It is interactive in the sense that the user can input some parameters and the program can interpret the parameters given and create a plot of the desired data file.
