After you have imported the data as suggested by Neil, it should be in the form of a list of lists. e.g.
data = {
{0.15, -4.0, -2.5, -6.5, -2.0, -8.5},
{0.25, -4.0, -2.5, -6.5, -2.0, -8.5},
{0.35, -4.0, -2.5, -6.5, -2.0, -8.5},
{0.45, -4.0, -2.5, -6.5, -2.0, -8.5}
}
One way to plot it is using ListPlot
with the x
value paired with each of the y
values.
plotData = Tuples[{{First[#]}, Rest[#]}] & /@ data
(* {{{0.15, -4.}, {0.15, -2.5}, {0.15, -6.5}, {0.15, -2.}, {0.15, -8.5}},
{{0.25, -4.}, {0.25, -2.5}, {0.25, -6.5}, {0.25, -2.}, {0.25, -8.5}},
{{0.35, -4.}, {0.35, -2.5}, {0.35, -6.5}, {0.35, -2.}, {0.35, -8.5}},
{{0.45, -4.}, {0.45, -2.5}, {0.45, -6.5}, {0.45, -2.}, {0.45, -8.5}}} *)
Then
ListPlot[plotData, PlotRange -> {{0, .6}, {0, -10}}]
