Works fine for me. See attached pdf. Also got an eps with appropriate
command but don't know how to look at it and check that it is the same as
the pdf.

GNU Octave, version 2.1.46 (powerpc-apple-darwin6.6).
GnuPlot 3.8h, and also old version of AquaTerm

octave:1> y=[97 89 67 62 50 41 35 25];
octave:2> x=1:8;
octave:3> koeff=polyfit(x,log(y),1);
octave:4> realkoeff=exp(koeff)
realkoeff =


octave:5> yp=polyval(koeff,x);
octave:6> plot(x,y,';verkligt antal;',x,exp(yp),';exponentiellt bortfall;');
