Hi Hauke,

Last time I checked, the version 5 Plot and ListPlot were working just
fine. (BTW unbelievable Hamburg University doesn't have 6 or 7, that
can't really be true).

The following works on my version 5.2:

f = Table[{x, Random[Real, {0.98, 1.02}] Sin[x]}, {x, 0, 2 =CF=80, =CF=80=
/20.}]
g = Table[{x, Random[Real, {0.9, 1.1}] Sin[x]}, {x, 0, 2 =CF=80, =CF=80/2=
0.}];

p1 = Plot[Interpolation[f][
        x], {x, Min[f\[Transpose][[1]]], Max[f\[Transpose][[1]]]}]

p2 = ListPlot[g]

Show[p1, p2]

If f is so smooth as you claim, you might consider dropping
Interpolation:

p1 = ListPlot[f, PlotJoined -> True]

Cheers -- Sjoerd
