You can simply copy then paste from your email into a Mathematica session and Mathematica will do the right thing. <data and ListPlot example snipped> >Instead of plotting some step curve (some values of the list were >multiple), it plotted only parts of the list (only the first value >in a series of multiple values). I don't understand what you were expecting but it looks to me as if ListPlot is performing exactly as documented. Note that Length[swk] 41 Length[Union[swk]] 6 and Take[swk, {-10, -2}] {{3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}, {3809.5051853424857, -0.002704921194676019}} That is there appear to be only 6 distinct pairs in swk When I do ListPlot[swk, PlotRange->All]; I see 6 points ploted And when I compare ListPlot[swk, PlotJoined->True, PlotRange->All]; I see 5 line segments joined a places corresponding to the plotted points. Given that you are plotting only 6 distinct points, why do you expect a different plot? -- To reply via email subtract one hundred and four
