|Graph => n'th Order Polynomial Fit|
n'th Order Polynomial Fit
Calculate a higher order polynomial fit by selecting n‘th order polynomial fit. GraphTool ask you in a dialog window for the grade of the polynomial fit. Grade one gives the linear regression again. The maximum grade is 32.000. The current grade will be displayed in a list box on the right side of the graph. You can delete the polynomial curve by selecting the option again and pushing the Delete PolFit button.
A polynomial fit needs a minimum of 3 data points!

The result(s) of the polynomial fit can be saved in a ASCII-file! As a standard GraphTool uses the filename extension *.sdg and the GraphTool file structure.
