Sure, use axis() to do it for each plot.

But if you are asking how you can tell Octave (or really, gnuplot) to

  set the axis for the second plot to the same axis that was
  automatically chosen for the first

or

  use autoscaling, but set both axes the same (i.e., use the max and
  min values of all subplots as the limits for all axes)

then I don't think there is a convenient way to do it given the
current limitations of gnuplot.
