This can be a normal numbering, as shown in the first sheet of the example file. Clear search A trendline is a line that's closest to all the values on average. In case of using polynomial equation you should follow the following formula in order to get the value of r2 because the point of r2 is located on (3,1) of matrix output. In your real worksheets, you should choose the trendline type corresponding to your data type. merci. The trend line is supposed to give a smoothed functional relationship based on some theoretically justifiable dependence. Any suggestion on how to fix this problem? Improve this question. All Rights Reserved. So secondly, you should display the trendline constants with maximum precision. I mean no need to wrap the TREND formula in Google Sheets with the ARRAYFORMULA function. (2) Same as (1), but use a cubic spline for the interpolation. About exponential trendline it appears =RSQ(Ln(Known_y's),(Known_x's)) to calculate R^2. Google Sheets Charts: Built-in Charts, Dynamic Charts, and Custom Charts. Another trick is to place dummy points in the extrapolated range to get the polynomial to behave *within* your desired range. The coefficients can be calculated by using these generic formulas: For our sample data set, the formulas take the following shape: a: =EXP(INDEX(LINEST(LN(C2:C13), B2:B13), 1, 2)). How can I get more digits of trendline function to get a more precise function? Also try using LINEST instead of relying on the trendline from the chart, as shown here EDIT: Having looked at this a bit more, there is something wrong with your X values in the original data. LINEST often gets the *wrong* answer for polynomials of order 3 or above. You can simply customize the chart and then add the line of best fit. glad to see people finding it useful, wish I could apply it too. Microsoft Excel plots the incorrect trendline when you manually substitute values for the x variable. I love the program and I can't imagine using Excel without it!
