In the default situation, GNUPLOT expects to see three or four numbers on each line of the data file, either (x, y, ydelta) or (x, y, ylow, yhigh). The following plot command shows setting the trange to [-pi:pi], the xrange to [-1.3:1.3] and the yrange to [-1:1] for the duration of the plot: plot [-pi:pi] [-1.3:1.3] [-1:1] sin(t),t**2 Other The xtics are not visible, because we set them to scale 0.
