the manual:
plt
[is] a non-interactive plotting utility originally written for
Unix by Paul Albrecht. plt
can produce publication-quality 2D plots
in PostScript from easily-produced text or binary data files, and can also
create screen plots under the X Window System. Compared to most other software
for 2D graphics, plt
has several significant advantages:
-
plt
generates compact vector PostScript output, which can be transmitted quickly yet can be resized without introducing raster artifacts. -
plt
works well with a wide variety of tools that create and manipulate readable text files. -
plt
is scriptable; if you need to make 100 plots of 100 data sets, you don't need to point and click for hours. -
Complex overlays and multi-part plots are easy to make, using multiple
invocations of
plt
to write to a single window or page. -
plt
can read data from a pipe, so it can be used to observe real-time signals or the outputs of computationally intensive processes as they become available. -
plt
imposes no fixed limits on the number of points in a plot (even the total amount of available memory is not a constraint if the data are read from a pipe and the axis limits are pre-specified). -
plt
is free, open-source software that can be modified as needed for unique applications. (plt
runs on all popular platforms, including GNU/Linux, Mac OS X, MS-Windows, and Unix.) -
plt
is easy to pronounce (say: P-L-T) and is almost as easy to spell :-)
Sources for the current version of plt
are available as a gzip
-compressed tar
archive, or as
individual files in the source tree. A source RPM and a
Linux (x86)
binary RPM are also available, as are binaries for
Mac OS X and
MS-Windows. The plt
Tutorial and Cookbook is available in HTML,
printable PostScript and PDF formats, and in LaTeX source format.
