xyExtract is a software tool that extracts 2D data from a graphic file featuring orthogonal and nonorthogonal axes. It can work with a range of file types, including scanned documents, PDFs, gifs, and jpegs.

This software provides a range of mathematical tools such as curve fitting, nonlinear regression, treatment of data, basic statistics, and error propagation. It also allows users to create 2D and 3D graphs with confidence band, uncertainty, error bars, and conduct tests such as chi-square and correlation coefficient. Additionally, it includes a covariance matrix for extrapolation.
