Re: Plotting multi-column data

The multi-column data has the form


{{x[1], y[1, 1], y[1, 2], y[1, 3], y[1, 4]}, {x[2], y[2, 1], y[2, 2], y[2, 3], y[2, 4]}, 
  {x[3], y[3, 1], y[3, 2], y[3, 3], y[3, 4]}}

To convert to plot data


{{{x[1], y[1, 1]}, {x[2], y[2, 1]}, {x[3], y[3, 1]}}, {{x[1], y[1, 2]}, {x[2], y[2, 2]}, 
   {x[3], y[3, 2]}}, {{x[1], y[1, 3]}, {x[2], y[2, 3]}, {x[3], y[3, 3]}}, 
  {{x[1], y[1, 4]}, {x[2], y[2, 4]}, {x[3], y[3, 4]}}}

Using numbers to demonstrate the plots
