Using the following data plot A B 0.000568 0.22 0.001136 0.05 0.00170 0.02 0.000136 0.97 0.000329 0.42 Plot and add a trend-line. Make the trend-line exponential and you get a garbage fit. If you multiply column A by 4, the fit works. Multiply by 3 and it fails. It appears that the algorithm used for this type of trend-line is flawed and has limitations that do not occur in MS Excel. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
