Troy - if you right-click on the trendline and format trendline there is an option at the bottom to display the line's equation, in this case y = 1.3714x + 81.2 I think that means the first point is 82.5714 and the last point is 89.4284. What’s more, the LINEST results below agree with the trendline: The exponential fit in Excel isn't really doing what I want it to do (the fitted exponential is clearly upside-down in the first graph) and I was wondering if there was an easy way to fix this or an explanation as to why it won't fit it the way I would like it to. The default is two, meaning it will take the average of every two data points. The Trendline object is a member of the Trendlines collection. I know that you can use the following formulae in Excel to fit a … Exponential trendline. Explanation: Excel uses the method of least squares to find a line that best fits the points. The basic reason for this suboptimal result is, that Excel does not determine the exponential coefficients directly, but calculates a linear trend for the ln(y) instead. The equation for an exponential curve is y = ae bx, where a and b are arbitrary constants and e is the mathematical constant e.In your curve, the constants have been adjusted so that a = 3E+07 ≡ 3.0 x 10 7 ≡ 30,000,000 and b = 1.8299. hide. If that’s still overfitting, just add more to smooth out the line. Plotting a logarithmic trend line in Excel. Log in or sign up to leave a comment Log In Sign Up.
