One-dimensional gnuplot (including time)

These options produce data suitable for using with the gnuplot visualization client in the format
t x f(t,x,y=fixed,z=fixed):

  IOASCII::out1D_every = 1
  IOASCII::out1D_vars = "wavetoy::phi"
  IOASCII::out1D_style = "gnuplot f(t,x)"

Output file: phi_x_[1][1].asc
