Joaqim,
You can create your Plot:
gp=Plot[Sin[x],{x,-Pi,2Pi}]
and your ListPLot:
gl=ListPlot[Table[Point[{x,Sin[x]}],{x,-Pi,2Pi,Pi/4}],
PlotStyle->PointSize[0.02]]
and then display them in one graphic using
Show[{gp,gl}]
Or you can add the Points directly in your Plot using Epilog:
Plot[Sin[x], {x, -Pi, 2*Pi},
Epilog ->
{PointSize[0.02],
Table[Point[{x, Sin[x]}],
{x, -Pi, 2*Pi, Pi/4}]}];
Epilog (and Prolog) are good to add any Graphics-stuff in a Plot.
es gruesst
