Abstract:

GRAFTEK is an interactive graphics program that fits by least squares, a curve to N data points. This code combines two CDC 274 graphics curve fitting programs GRAFFIT, LSQ for use on the TEKtronix 4014 storage tube using Tektronix software TCS. The program fits the curve and determines the constants for any of nine empirical equations or a polynomial of up to 11th degree, and displays the fitted curve up to three at one time against a background of the data points. Options include reading in new data, rescale of axes, deleting all displayed curves, deleting points, adding new points, restoring all original or selected deleted points, specifying constants, and calling for CALCOMP plotter or quick look hard copy of output.
