copy trendline logarithmic constants to a cell
David -
Excel's logarithmic trendline fits y = c*LN(x) + b. Excel's exponential trendline fits y = c*EXP(b*x). Excel's LOGEST function fits y = b*m^x. The b value corresponds to c in the trendline exponential function, and the m corresponds to EXP(b). So, LOGEST is a worksheet equivalent to exponential trendline, not to logarithmic trendline. - Mike www.mikemiddleton.com "David Biddulph" wrote in message ... "Cheetha" wrote in message ...
