Package plotutils: Information

The GNU plotting utilities include:
(1) GNU libplot, a shared library for exporting 2-D vector graphics
files and for performing vector graphics animation under the X
Window System. Its output file formats include pseudo-GIF, PNM, Adobe
Illustrator, Postscript (editable with the free 'idraw' drawing editor),
Fig (editable with the free g' drawing editor), PCL 5, HP-GL and HP-GL/2,
Tektronix, and GNU metafile format. Many Postscript, PCL, and Hershey
fonts are supported. A separate class library, 'libplotter', provides
a C++ binding to libplot's functionality.
(2) Sample command-line applications 'graph', 'plot', 'tek2plot',
'pic2plot', and 'plotfont', which are built on top of GNU libplot. 'graph'
is a powerful utility for XY plotting, 'plot' translates GNU metafiles to
other formats, 'tek2plot' translates legacy Tektronix data, 'pic2plot'
translates box-and-arrow diagrams in the pic language, and 'plotfont'
plots character maps.
(3) Command-line applications 'spline', 'double', and 'ode', which are
useful in scientific plotting. 'spline' does spline interpolation of input
data of arbitrary dimensionality. It uses cubic splines, splines under
tension, or cubic Bessel interpolation. 'ode' is an interactive program
that can integrate a user-specified system of ordinary differential
equations.
