SigmaGraph is a data plotting and analysis software designed to be lightweight, reliable and easy to use. SigmaGraph runs on Windows 2000, XP, Vista and Windows 7, and will be ported to GNU/Linux and Mac OS X. SigmaGraph offers almost all the functionality needed by scientists and engineers: editable datasheets (column properties, create series, set column values by using any mathematical expression, show column statistics, import/export from/to ASCII file, mask and unmask cells, printing, etc.); scientific graphing with a complete control of the graph (line/symbol style, colors, fonts, legends, axis properties, grid, tick, labels, scale, auto scale, log/linear scale, zoom in/out, copy format to another graph, export as image, printing, etc.); curve fitting (up to twenty models including linear, polynomial, exponential, Gaussian, Lorentzian, Pearson VII, logistic, power, etc. and user-defined models); error bars (percentage, constant or any user defined data); drawing tools (line, rectangle, ellipse); mathematical console; Scripting engine; etc.
