When you decide how long the Line should be, draw the Line(s) in a Prolog or Epilog. sa[x_ /; x == 0] = 1; sa[x_] := Sin[x]/x; Plot[sa[x]^2, {x, 0, 2Pi}, PlotStyle -> {RGBColor[0, 0, 1], AbsoluteDashing[{5, 5}]}, Prolog -> {RGBColor[1, 0, 0], Table[Line[{{x, 0}, {x, sa[x]^2}}], {x, 0, 2Pi, Pi/10}]}]; Bob Hanlon In a message dated 2001/4/20 4:45:20 AM, ulbrich at biochem.mpg.de writes: >does anybody know if there is a possibility >to include the DiracDelta[] in a Plot? >If I have > >Plot[DiracDelta[x-1],{x,0,2}] > >I see nothing, but I would like to see >a vertical line at x=1.
