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. -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept. phone 413 549-1020 (H) Univ. of Massachusetts 413 545-2859 (W) Amherst, MA 01003-4515
