DISLIN is a high-level, easy-to-use plotting library for displaying data as curves, bar graphs, pie charts, 3D-colour plots, surfaces, contours, and maps. Several output formats are supported, such as X11, VGA, PostScript, PDF, CGM, HPGL, TIFF, and PNG. Plotting extensions for the interpreting languages Perl, Python, and Java are also supported for most operating systems.
EGO is a program to perform molecular dynamics simulations on parallel as well as on sequential computers. Supported parallel machines include the Hitachi SR8000, CRAY-T3E, IBM-SP2, Fujitsu VPP700, Parsytec-CC under PARIX, and inhomogeneous clusters of UNIX workstations under PVM or MPI. EGO also runs sequentially on any decent UNIX workstation, even Windows95/NT PC's (with a GNU-C compiler) can be used.
GraphPak is a programming library of 2D and 3D charting objects for the Qt toolkit. It provides software developers with a set of C++ objects to easily create charts or graphs that aid in the visual presentation of technical and business data. This release includes Bar, Line, Pie, Ring, Area, Hi-Lo, Box and Whisker, and Polar charts. It is based on the KD Chart product from Klarälvdalens Datakonsult AB.
KVEC is a command line tool that allows you to convert raster graphics to vector graphics. KVEC is designed for 32 bit operating systems and runs on Win32, OS/2, HP-UX, NEXTSTEP, Linux, IRIX, AIX 4.x, Macintosh and BeOS. Docs are available in English and German. The shareware version is available for 30 day trial.
QCad is a powerful but easy to use 2D CAD program for Linux, Windows, and Mac OS X. It uses DXF as its standard file format. While other CAD packages are often rather complicated to use, QCad tries to stay comfortable, and even an absolute beginner can create professional drawings with a minimum of effort.
SigLab is a calculator designed for working on signals. You can use it to load, save, or generate signals, and do various operations on and between signals (addition, log, abs, sin, filtering, convolution, fft, correlation, etc.). Signal parts are constantly displayed. SigLab was designed to be able to handle the results of simulations or measurements. It can handle signals with millions of points, keeping in memory a small piece of each signal. To keep good performance, it caches in memory signal portions. SigLab was specifically designed for Ptolemy users. It will start at the end of a simulation and show all asked signals.
The Snack sound extension adds commands for sound play/record and sound visualization, e.g. waveforms and spectrograms. It supports in- memory sound objects, file based audio, streaming audio, WAV, AU, AIFF, and MP3 file formats, synchronous and asynchronous playback. The visualization canvas item types update in real-time and can output postscript. New commands and file formats can be added using the Snack C-API.
PLOTICUS is a command line utility for creating bar, line, pie, boxplot, scatterplot, sweep, heatmap, vector, timeline, Venn diagrams, and other types of charts and plots. ploticus is good for automated or just-in-time graph generation. It handles date, time, and categorical data nicely, and has some basic statistical capabilities. It can output to GIF, PNG, SVG, SWF, JPEG, PostScript, EPS, and X11. You can use convenient preset options or create complex scripts with rich and detailed color and style operations.
