The Data Touring Machine
This is a reconstruction of the original page (http://www.datoura.org).
Datoura is a
small simple set of data graphing lisp routines that generate postscript
output. Generating postscript eliminates the need for X graphics
libraries, but you must have a postscript viewer installed (for Linux
for Windows gsview)
The command style is borrowed from Mathematica, postscript and,
of course, lisp with a set of "graphics primitives" such as points,
lines, circles, polygons and "postscript-directives" which pass commands
through directly to the postscript interpreter.
Some handy plots are built from the primitives such as
histogram, scatter-plot, profile, function-plot and parametric-plot.
Plots are generated and shown separately which allows you to build many
plots and show them superimposed with proper axis-handling. Multiple x
and y axes are supported, too.
Datoura was written in CLISP
on linux and cygwin, but has been tested (without some of the bells and
whistles) in gcl. It
should work in any common lisp implementation, but I haven't done much
testing. Datoura also works in a windows platform with the help of the
IDE by Krzysztof Włodarczyk VisualCLisp (sorry about the stale link)
