The Fitting Tool can try fitting known expressions to an active plot in the current graph. If more than one active plot exists, then plots can be merged before fitted. 1D/2D/3D fittings are available. The explicit expression obtained by the fit can be copied to clipboard (in latex format) or be tagged within the current graph. The fit can be saved to a file as a fit profile and be used to evaluate data within the various modules, Command Syntax and New Graph Tool. Basic algebraic function, such as derivatives and integrals, can be made by the Algebraic Tool on the expression obtained.
