plot discrete spectrum

Is there an easy way to do a ListPlot[{{{x1, y1}, {x2, y2}, ..., {xn,
yn}} in which each a perpendicular is dropped from each dot to the
horizontal axis?

Of course, when can combine the ListPlot with a Graphics object
consisting of line segments.  I prefer a way that avoids using graphics
primitives directly.

The sort of plot I want is what's usually done to display, for example,
the energy spectrum of a Fourier series.
