Polynomial trendline in Excel. This curve features alternate increase and decrease. The degree (by the number of minimum and maximum values) is determined for polynomials. For example, one extreme (minimum and maximum) is the second degree, two extremes make the third degree, three extremes – the fourth one. Select the scatter chart, and then click the Add Chart Element > Trendline > More Trendline Options on the Design tab. 4 . In the opening Format Trendline pane, check the Polynomial option, and adjust the order number in the Trendline Options section, and then check the Display Equation on Chart option.

Any help would be greatly appreciated. The Excel Linest function and polynomial chart trendline produce different results for 6th order polynomials in the cases examined. As noted by Lori Miller in the comments to the previous Linest post, this is probably because of changes made to the algorithm for dealing with co-linear data. The formula you would have to type for example is this. Say for example we put a value in the A column, say A2, and wish to compute the value of the polynomial in the B-column, in cell B2. The formula I would have to type would be: =A2^3+2*A2^2+8*A2+1 or =power(A2,3)+2*power(A2,2)+8*A2 + 1 Again, you can use Autofill or use an Excel table to do this. For any polynomial equation, LINEST returns the coefficient for the highest order of the independent variable on the far left side, followed by the next highest and so on, and finally the constant. A similar technique can be used for Exponential, Logarithmic, and Power function curve fitting in Excel as well.
