Now I=C2=B4ve got the misstake.=20 You are right. The Problem was that gnuplot gets zero in the common denomin= ator.=20 The Problem was, that I gave the start value d=3D30. In my data there was a= n x=3D30 and because of that gnuplot gets zero for x-d in the first run and= fails.=20 I solved the problem with commenting that value out so that I got a better = value for d, d=3D30.0398. Then I put the problematical x=3D30 back into my = list of data and gave the new start value d=3D30.0398 to gnuplot. Then it f= itted the Funktion. Thank you both. Fleur
