Is it possible to copy trendline logarithmic constants to a cell for further
calculations.

For my enhancements to Dave Braden's code to do the needful:

To get the results directly in a worksheet:

Can't you use the LOGEST() function?

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.
