- GNU Plotting Utilities
/Main/Other/i386/Applications/Graphics/
The GNU plotting utilities include: (1) Sample command-line applications
`graph', `plot', `tek2plot', and `plotfont', which are built on top of the
GNU libplot DLL. `graph' is a powerful utility for XY plotting, `plot'
translates GNU metafiles to other formats, `tek2plot' translates legacy
Tektronix data, and `plotfont' plots character maps. (2) GNU libplot, the
underlying DLL for two-dimensional device-independent vector graphics and
vector graphics animation under the X Window System. Output formats
include X11, Adobe Illustrator, Postscript (editable with the free `idraw'
drawing editor), Fig (editable with the free `xfig' drawing editor), PCL 5,
HP-GL and HP-GL/2, Tektronix, and GNU metafile format. Many Postscript,
PCL, and Hershey fonts are supported. (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.
