Dear John, the horizontal line is the x-axis; use the option Axes->False to plot your data: Test = Table[{x, (1/ 2) + (Cos[2*2*Pi*x]/ 2)*(E^-(x^2) + (1/2)*0.1*E^-((x - 12)^2) + (1/2)*0.05* E^-((x - 27)^2) + (10^-3)*E^-((x - 280)^2))}, {x, -10, 40, 0.05}]; ListPlot[Test, PlotRange -> All, Joined -> True, Frame -> True, FrameLabel -> {"Pathlength Mismatch (2\[CenterDot]m mm)", " Signal Strength "}, BaseStyle -> {FontFamily -> "Garamond", FontSlant -> "Italic", FontSize -> 14}, Axes -> False] Ricardo On 10/6/07, john.feth at honeywell.com <john.feth at honeywell.com> wrote: > > I'm using Mathematica 6.0 and when I use the following notebook entry > > Test=Table[{x,(1/2)+(Cos[2*2*Pi*x]/2)*(E^-(x^2)+(1/2)*0.1*E^- > ((x-12)^2)+(1/2)*0.05*E^-((x-27)^2)+(10^-3)*E^-((x-280)^2))}, > {x,-10,40,0.05}];ListPlot[Test,PlotRange->All,Joined->True,Frame- > >True,FrameLabel->{"Pathlength Mismatch (2\[CenterDot]m mm)"," Signal > Strength "},BaseStyle->{FontFamily->"Garamond",FontSlant- > >"Italic",FontSize->14}] > > in addtion to the plot I want, I get a horizontal line across the > whole plot at 0.2.
