GNU Plotting Utilities

The GNU plotting utilities consist of seven command line programs: the graphics programs `graph', `plot', `tek2plot', and `plotfont', and the mathematical programs `spline', `ode', and `double'. GNU `libplot' is distributed with these programs; it is the library on which the graphics programs are based. `Libplot' is a function library for device-independent two-dimensional vector graphics, including vector graphics animations under the X Window System.
