The setting is applied with recalculation.
Different functions can be adapted to data with the calculator: fit linear, fit polynomial, fit Fourier series, fit Gaussian distribution and fit power law. By calculating the respective best-fit line the graph is reset and the measured values and the best fit line is drawn. Through the selection of further compensation functions the other functions are added to the chart. The representation of functions and points can be selected by means of the style information. The Style entries will be published with recalculation. σ shows the standard deviation of the points to the calculated function.
Enter measurements: x1, y1, x2, y2, ...
An alternative input is possible via the box below. The decimal separator is the period (.). The values may be separated comma or space or semicolon. It is important that the final number will be terminated with a semicolon.
