2D data plotting environment - consists of a standalone Tool for 2-D visualisation of data files after the data is generated (postprocessing) and an optional C++ graphics library for visualisation of data while data is generated (online processing). Draws multiple graphs in a plot (a window) and multiple plot windows in one session. It offers different graph types (lines, bars, stairs, stems), styles (color, width, marker, ...) and a legend. The mouse is highly supported with zoom, auto range and drag&drop of files. The data itself is stored in ascii files, plot style and session information in separate files. Copy and print are available in black&white or coloured format. Storage as EMF-File is supported. The optional programmer's library supports all features from above with access functions. User's and programmer's interface are simple and intuitive. Both are additionally documented in detail. Funplot offers an illimited number of data storage (only by PC memory) and has small requirements for CPU, RAM and harddisk. The evaluation version has complete functionality with the only limitations of the display of the word "Demo" in the graphics window and the "Unregistered About" Screen at start.
