AW: Identical functions not identical ?!

I can't reproduce the problem:

p1 = Plot[Sin[x], {x, 0, 2*Pi}]
p2 = Plot[0.95*Sin[x], {x, 0, 2*Pi}, PlotRange -> {{0, 3*Pi}, {-1, 1}}]
Show[p2, p1]

works absolutely fine.

Show some code example.

Betreff: [mg45960] Identical functions not identical ?!

Dear Group,

I define two plots of the same function, but with
different range for the independent variable.

Combining them without options, the two plots

But if I want to enlarge a certain range of the
independent variable (using PlotRange) deviations
become visible.

Why is that and how can I suppress that ?

Thanks a bunch in advance,
