It should be fairly simple in this case: data=Import["<path>\\data.txt","CSV"]; ListPlot[Rest[data]]; There are many options to ListPlot that will allow you to format the resulting plot to a format that you desire. For example: ListPlot[Rest[data], Frame -> True, Axes -> False, PlotJoined -> True, FrameLabel -> {"Wavelength", "Detector Reading"}, PlotLabel -> data[[1, 1]]]
