In one instance I need the x and y values from the peak of the curve, calculated automatically. A scatter chart is one that uses dots to represent. 1 I have a variety sheets with x-y scatter charts displaying polynomial trendlines. The data you select will be used to create your scatter chart. The "new_x" values are in cells A24:C24, where B24 and C24 are the formulas as shown. 1.Highlight the data you want to analyze. The "known_y" values are in green in E3:E22 The "known_x" values are in green in A3:C22 If you change the values in E3:E22, the trend() function will update Cell E24 for your new input at Cell A24.Įdit = The trend() formula is in Cell E24 where the cell references are shown in red.Ĭell A24 contains the new X, and is the cell to change to update the formula in E24Ĭell B24 contains the X^2 formula (A24*A24) for the new XĬell C24 contains the X^3 formula (A24*A24*A24) for the new X Column C is X^3 (two cells to the left cubed). Column B is X^2 (the cell to the left squared). ![]() Try trend(known_y's, known_x's, new_x's, const).Ĭolumn A below is X.
