(How is my net-iquette? I'm new at this...) Check out the plplot library. Here is the README file... --Mark This is the distribution for PLplot, a scientific plotting package. PLplot is relatively small, portable, freely distributable, and is rich enough to satisfy most users. It has a wide range of plot types including line (linear, log), contour, 3D, fill, and almost 1000 characters (including Greek and mathematical) in its extended font set. The package is designed to make it easy to quickly get graphical output; only a handful of function calls is typically required. For more advanced use, virtually all aspects of plotting are configurable. The PLplot package is distributable under the terms of the GNU Library General Public License (LGPL) with some exceptions -- see the file "Copyright" for full information. The intent here is to ensure that PLplot continues to evolve in a positive way, while remaining freely distributable. Placing the library under the LGPL enables software developers to use the PLplot library as an integral part of their product, even a commercial product. We welcome suggestions on how to improve this code, especially in the form of user-contributed enhancements or bug fixes. If PLplot is used in any published papers, please include an acknowledgment or citation of our work, which will help us to continue improving PLplot. Also, please remember that as PLplot is not a commercial product, we cannot be expected to offer the kind of support that a commercial product may. There is great interest in extending PLplot and fixing bugs, but the principal authors can only afford to work on it part time. Improvements will necessarily focus on those which help us get our work done. PLplot is written in C, enabling it to run on many platforms practically without modification. Fortran programs may use it transparently; stub routines are provided to handle the C<->Fortran interface without any modification of the user program. C programs are required to include the header file "plplot.h"; see the documentation for more details. The main documentation for PLplot is in the doc/ directory in the form of several TeX files; please consult this for additional information ("latex plotdoc"). Unfortunately documentation tends to lag actual improvements to the code, so don't be surprised if some known features are not explained there. Consult "NEWS" to see a list of recent changes. At present, PLplot is believed to work on the following systems: Unix: AIX (IBM) ConvexOS (Convex) DG/UX (Data General) HP-UX (Hewlett-Packard) IRIX (Silicon Graphics) Linux (various) OSF/1 (DEC) SunOS (Sun) Super-UX (NEC) SysV (various) Ultrix (DEC) Unicos (Cray) Amiga/Exec MS-DOS OS/2 NeXT VMS Many different output device drivers are available, including postscript, tektronix, HP laserjet, HP pen plotters, XFig, xterm, X-windows, and a portable metafile format, among others. The Tk driver under Unix/X provides a full user interface based on the plframe plotting widget (see below). The Tcl-DP based driver is a variant of the Tk driver that supports distributed rendering. The metafile renderer (plrender) supports all of the standard operations as well as seeking operations (backward, forward, or to any specified page) when interactively viewing metafile output. Part of the PLplot package is a Tcl-based interpreter (pltcl). This program allows interactive plotting using the Tcl script language with plotting extensions. Currently about half of the PLplot library functions are recognized from the Tcl side, with more to follow. Also part of PLplot is a Tk-based plotting widget, called a plframe. This widget is based on the Tk frame widget, and supports a variety of user options such as zoom, scrolls, save to a variety of devices, print, resize, page layout, orientation change, and palette manipulation. Direct plotting to the widget may be done by calls to the underlying library using either C or Fortran bindings, and a large number of operations can be interpreted directly (in Tcl) by the widget. For more information on how to get or use PLplot on your system, see: - appendices to the PLplot manual - system-specific documentation in the appropriate sys/ directory.
