Many thanks! It isn't clear to me whether you want separate plots or everything on one plot. First, generate so test data, i.e., data = Table[{x, 2x, x^2, x^3}, {x, 0, 1, .05}]; then ListPlot[data[[All, {1, #}]]]&/@Range[2, 4]; will generate separate plots with the first column being the x-axis for each and Show[Block[{$DisplayFunction = Identity}, ListPlot[data[[All, {1, #}]]]&/@Range[2, 4]]]; will generate a single plot with the first column being the x-axis -- To reply via email subtract one hundred and four
