Hello David,
I am not sure I understand your question accurately, but if I do
understand, then this may be a preferable solution to your problem:
(*fresh kernel*)
test = Table[{x, Sin[n Pi x]}, {n, 1, 5, 1}, {x, -Pi, Pi, Pi/50}]; (*
supply x and y explicitly *)
ListPlot[test]
ListPlot[test, Joined -> True]
ListLinePlot[test]
This is a lovely example by the way---I am going to use it as a
problem for students to calculate fourier coefficients from data: give
'em the points randomly, extract the coefficients, plot separate
curves...
