Dataplot

DATAPLOT is a public-domain, multi-platform software system for performing scientific visualization, statistical analysis, and non-linear modeling. It was developed in response to data analysis problems encountered at the National Bureau of Standards (now the National Institute of Standards and Technology).

DATAPLOT is primarily written in Fortran-77, highly portable, and can be installed on any device operating on Unix, Linux, Mac OS X, and Windows operating systems. DATAPLOT is designed for researchers and analysts engaged in the characterization, modeling, visualization, analysis, monitoring, and optimization of scientific and engineering processes.

DATAPLOT Raw graphics including 2D, 3D, character/line/spike/bar plots, auto-labeling, auto-scaling, legends, sizing, etc. DATAPLOT also contains Analysis graphics; plotting data, plotting functions, mixing data and functions, plotting modeling residuals, Presentation graphics; Hershey fonts, Greek, math, word charts for slides, 3-D bars, Postscript, Summary graphics.

Pie charts, histograms, stratified histograms, Pareto charts, error bar plots, X-Y plots, etc., and diagrammatic graphics; Geometric symbols, electrical symbols, logic diagrams, schematics, etc. DATAPLOT features Graphical data analysis, Exploratory data analysis, Time series analysis, Multivariate analysis, as well as general data analysis such as location/variation/randomness/distribution summaries, t-test, Chi-squared tests, F tests, ANOVA, general transformations, subset analyses, and Youden interlab plots.

DATAPLOT Statistics/Probability Calculations functions include summary tabulation and cross-tab, library of probability functions, cdf's, pdf's, on-line auxiliary file of common probability functions, random number generation, random permutations generation, simulation, moment calculations, stat calculations, and stat subset plots. DATAPLOT also helps perform the following mathematical operations; plotting functions, roots, analytic differentiation.

Integration, convolution, extensive library of math functions, complex arithmetic operations, complex roots, FFT, matrix operations (inverse, norm, minor, eigenvalues, eigenvectors, etc.), set operations (union, intersection, Cartesian product, etc.}, polynomial arithmetic operations, logical set operations (and, or, nand, nor), differential equation solver, and fractal plots, and fractal plots. DATAPLOT can be downloaded via the web. Pre-built executable files are available for several common Linux/Unix platforms, Mac OS X, and for Windows XP/VISTA/7/8.
