Best plotting software for free download

Sometimes users of one local area network face the following problem: whether it is necessary to buy another scanner if you already have one in office or at home just for everyone to be able to scan documents without distracting colleagues from their important work? The BlindScanner software will share and open access to a scanner on the local area network that is not directly connected to your computer, but installed on a computer located in the neighboring room, for example. Easiness of use, saving to various formats, compressing images, scanning pages automatically, scanning multiple pages, supporting an automatic feeder - these are not all program features. The program will be useful not only in office where it will help you save several hundred dollars you could spend on a new scanner, but also at home for scanning from a notebook in a wireless home local area network. BlindScanner works with any plotting TWAIN scanner and also supports scanners with automatic feeders.

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.

FindGraph is a comprehensive graphing, curve fitting, and digitizing tool. FindGraph offers 12 generic fits, including linear regression, logistic functions, fourier approximation, neural networks, B-splines and parametric curves least squares approximations, plus a library of over 300 industry-specific 2D formulas. FindGraph uses the Levenberg - Marquardt non-linear algorithm and the Simplex algorithm to fit data. A built-in Wizard helps to apply different curve fits to discover the model that best describes the data. Peak fitting features are included. The latest version includes a feature that applies Singular Spectrum Analysis (SSA) to reconstruct and to forecast data series. The software enables you to smooth, interpolate, apply FFT and Wavelet filters, subtract, differentiate, integrate, transform data and curves, and to apply Procrustes analysis. The program comes with 200 built-in common graphing 2D functions support for polar, Cartesian, and parametric equations. A built-in Wizard helps to digitize the data. The program supports OLE automation and can be built-in to other software applications.
