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.
