This is an application to help user (mathematician) to make regression between series of data, draw grpahics, and export them into various formats by means of common graphics packages (i.e., gnuplot, plotutils). It is written in Python. The user interfeace is built upon the wxPython (wxWindows) widget set. The idea of usage is as follows: the user builds a project which is represented as a tree of modules; modules can generate data variables, as well as consume them. Essentialy, such a tree represents an algorithm of data analysis. The system is intended to educate students.
PLplot is a library of C functions that are useful for making scientific plots from programs written in a wide variety of languages. It can be used to create standard x-y plots, semi-log plots, log-log plots, contour plots, 3D plots, shade (gray-scale and color) plots, mesh plots, bar charts, and pie charts. Multiple graphs may be placed on a single page with multiple lines in each graph. Different line styles, widths, and colors are supported. A virtually infinite number of distinct area fill patterns may be used. A variety of output devices and file formats are supported.
Teddy is an OpenGL-based 3D graphics library written in C++. Its main features are simple scene graph and windowing system-enabling multiple cameras, camera windows, and scenes. It focuses on easy and flexible manipulation of models and model materials in the scene graph. It contains a number of primitive objects like sphere, box, and cone, and it can load LightWave object and scene files.
pygps is a GPS user interface. It shows a listing of satellites, their locations in the sky, a list of latitude, longitude, altitude, status, etc., and moving maps. It was designed to work on the Compaq (now HP) iPAQ PDA running Linux, with a 240x320 screen. However, it uses glade, so that it also works nicely on larger screens, or on a landscape orientation of 320x240. It works with any GPS receiver supported by gpsd (which see).
Medoosa is a documentation tool for C++ that can produce UML class diagrams, including generalizations and associations. Corrections can be made interactively in a diagram editor (Dia) and are fed back into the source as Javadoc-style comments. The layout must still be done by hand.
