PROGRAM:
NAME
pyxplot - a multi-purpose command-line data processing, vector graphics and graph-plotting
tool.
SYNOPSIS
pyxplot [file ...]
DESCRIPTION
Pyxplot is a multi-purpose graph plotting tool, scientific scripting language, vector
graphics suite, and data processing package. Its interface is designed to make common
tasks -- e.g., plotting labelled graphs of data -- accessible via short, simple, intuitive
commands.
But these commands also take many optional settings, allowing their output to be fine-
tuned into styles appropriate for printed publications, talks or websites. Pyxplot is
simple enough to be used without prior programming experience, but powerful enough that
programmers can extensively configure and script it.
A SCIENTIFIC SCRIPTING LANGUAGE
Pyxplot doesn't just plot graphs. It's a scripting language in which variables can have
physical units. Calculations automatically return results in an appropriate unit, whether
that be kilograms, joules or lightyears. Datafiles can be converted straightforwardly
from one set of units to another. Meanwhile Pyxplot has all the other features of a
scripting language: flow control and branching, string manipulation, complex data types,
an object-oriented class structure and straightforward file I/O. It also supports vector
and matrix algebra, can integrate or differentiate expressions, and can numerically solve
systems of equations.
A VECTOR GRAPHICS SUITE
The graphical canvas isn't just for plotting graphs on. Circles, polygons and ellipses can
be drawn to build vector graphics. Colors are a native object type for easy customisation.
For the mathematically minded, Pyxplot's canvas interfaces cleanly with its vector math
environment, so that geometric construction is easy.
A DATA PROCESSING PACKAGE
Pyxplot can interpolate data, find best-fit lines, and compile histograms. It can Fourier
transform data, calculate statistics, and output results to new datafiles. Where fine
control is needed, custom code can be used to process every data point in a file.
Examples of the graphical output produced by Pyxplot can be found on the Pyxplot website:
