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.
