I tried saving some 4-column data to a file and using

  plot 'foo.dat' w v t ""

and gnuplot complained:

  gnuplot> plot 'foo.dat' w v t ""
                              ^
           expecting 'lines', 'points', 'linespoints', 'dots', 'impulses',
          'yerrorbars', 'xerrorbars', 'xyerrorbars', 'steps', 'fsteps',
          'histeps', 'filledcurves', 'boxes', 'boxerrorbars', 'boxxyerrorbars',
          'vectors', 'financebars', 'candlesticks', 'errorlines', 'xerrorlines',
          'yerrorlines', 'xyerrorlines', 'pm3d'

so what is a valid gnuplot plotting command that works so I can
understand what you are trying to plot.
