an image, data, and function plotter
This is an image, data, and function plotter. Function parameters can be manually tuned [or automatically fitted - not yet implemented] to given xy data. High-level scripting capability is provided [not yet] by the underlying Python programming language.
Descartes is platform independent; it runs under Linux as well as under non-free operating systems.
Descartes is open source software; it is distributed for free, and protected by the GNU public licence.
Here the overlay of a greymap (.pgm) image and a parabola:
Bad news: descartes is broken. The scipy library on which it depends has undergone a major reorganisation; the scipy.plt module is no longer supported. Is there anyone willing to change descartes' plotting frontend from scipy.plt to matplotlib?
The latest stable release is 0.7 (10 Jul 2005).
Fit and script capabilities are not yet implemented.
Usage of the program is fairly intuitive; the user manual currently contains only a few notes on special topics such as mathematical formulae and input data formats.
The program runs on any decent PC. The only requirement is a Python installation with SciPy and wxPython modules. All of this is freely avalilable on the net. See the download and installation instructions.
Feedback and further contributions will be welcome.
