FindGraph

If you are looking for a comprehensive graphing, curve fitting, and digitizing tool, then FindGraph may be the software for you. One of the main benefits of using FindGraph is that it offers 12 generic fits, such as linear regression, neural networks, and parametric curves least squares approximations, that can help you to discover the model that best describes your data. It also includes a library of over 300 industry-specific 2D formulas.

Additionally, FindGraph uses the Levenberg - Marquardt non-linear algorithm and the Simplex algorithm to fit data, and it includes peak fitting features. Singular Spectrum Analysis (SSA) is a beneficial feature that can help you to reconstruct and forecast data series and to extract cyclic signals. The latest version even includes an autoregression (ARIMA) model.

With FindGraph, you can apply various data manipulation techniques, such as smoothing, interpolating, and transforming data, as well as subtracting, differentiating, and integrating curves. The Douglas-Peucker algorithm and the empirical mode decomposition (EMD) algorithm are also included.

To further support your data analysis needs, the program comes with 200 built-in common graphing 2D functions, which support polar, Cartesian, and parametric equations. Additionally, the built-in digitizing wizard can help you to easily digitize your data. Finally, the software supports OLE automation and can be built-in to other software applications for seamless integration. Overall, if you want a feature-rich graphing and data analysis tool, then FindGraph is definitely worth considering.
