I have a datafile with lines like 171023_15h11m59s150 <value2> <value3>. I know how to plot columns 2 and 3 using set xdata time; set timefmt "%y%m%d_%Hh%Mm%Ss" My model is a = .028; b=.04; model(x) = a*x + b. When I say fit modele(x) "mystuff.txt" using 2:3 via a, b I obtain: No data to fit What is the right way to do? Regards, -- Jean-Pierre Coulon
