The Fit sub menu allows the user to fit one of three curves to the data within the active chart display - lines, exponentials, and Gaussians. Fit- ting is done using the Marquardt 'Gradient-expansion' algorithm to mini- mize chi-squared.

Pressing this key starts the actual fit calculations. While calculations are in progress, the "Calculating fit..." message is displayed at the bottom of the screen. The algorithm is designed to iterate until the change in chi- squared falls below 0.1%, although the fit may be terminated at any time by pressing the Abort (Return) softkey. The value of chi-squared is shown after each iteration.

When the fit terminates, the best fit curve is plotted and the parameters of the fit are displayed in a window at the center of the screen. Pressing any key to continue will remove the parameter window while leaving the best fit curve on the display. Pressing another key to continue will remove the curve and restore the graph to normal. See View Parameters below for a description of each fit.

This function toggles the Type of Fit between line, exponential, and Gaussian. The fit takes place only within the fit region defined by the Left and Right Limits (see below) on the active chart graph.

The View Parameters function displays the most recent curve fit and parameter window. For example, if a fit was performed and then the Fit menu exited, the fit will be erased from the screen. If the graph is then scaled differently using the Display Scale menu and then the Fit menu
