graphics/plotutils 2.6nb4 NetBSD

The GNU plotutils package contains programs for plotting scientific data, and a function library for drawing vector graphics and doing vector graphics animations. The package includes: * GNU graph, which does two-dimensional plotting in real time. It's designed for command-line use, and can be used in shell scripts. It produces output on an X Window System display, in Illustrator format, in Postscript format, in PCL 5 format, in HP-GL/2 format, in Fig format (editable with the xfig drawing editor), in Tektronix format, or in GNU Metafile format. Output in Postscript format may be edited with the idraw drawing editor. * GNU plot, which translates GNU Metafile format to any of the other formats. * GNU tek2plot, for translating legacy Tektronix data to any of the above formats. * GNU plotfont, for displaying character maps of the fonts that are available in the above formats. * GNU spline, which does spline interpolation of data. * GNU ode, which numerically integrates a system consisting of one or more ordinary differential equations.

The programs graph, plot, tek2plot, and plotfont are based on GNU libplot, a C function library for device-independent two-dimensional vector graphics. GNU libplot is compatible with the traditional Unix libplot library, but is much more powerful. It is installed as part of the package.
