How to correctly do a curve fitting

I am trying to do an exponential fit for a x and y dataset (see attached Figure, upper one). I used the exp (or exp_XOffset) function under "Analysis"--"Curve fitting" and got something weird (se attached Figure, lower one). Did I use the wrong function or? Or is there a way to simply draw a line (y=0.4 exp(0.05x)) manually?
Thanks!!

SetScale/I x, 0,16, "", ewave

ewave = 0.4*exp(0.05*x)
