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:
pltgenerates compact vector PostScript output, which can be transmitted quickly yet can be resized without introducing raster artifacts.
pltworks well with a wide variety of tools that create and manipulate readable text files.
pltis 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
pltto write to a single window or page.
pltcan 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.
pltimposes 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).
pltis free, open-source software that can be modified as needed for unique applications. (
pltruns on all popular platforms, including GNU/Linux, Mac OS X, MS-Windows, and Unix.)
pltis 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
tar archive, or as
individual files in the source tree. A source RPM and a
binary RPM are also available, as are binaries for
Mac OS X and
Tutorial and Cookbook is available in HTML,
printable PostScript and PDF formats, and in LaTeX source format.
