Hi,

something like this ?


AmplitudePlot[l : {{_, _} ..}, opts___] :=
    Show[Graphics[{{AbsolutePointSize[4.5], Point /@ l}, 
        Line[{{First[#], 0}, #} ] & /@ l }, opts]]


AmplitudePlot[l : {_?NumericQ ..}, opts___] :=
    AmplitudePlot[MapIndexed[{First[#2 - 1], #1} &, l], opts]


Regards
  Jens
