Alignment of subplots?

[Matthias Brennwald]

Dear all

If I plot two (or more) figures below each other using subplot, the
plots may end up un-aligned at the left (such as in the example below).
I use Octave 2.9.16 and Gnuplot. Is there a way to align the plots?

Code example:

x=[1:10];
y1 = rand(size(x));
y2 = 1e10*y1;
subplot(2,1,1);
plot(x,y1);
subplot(2,1,2);
plot(x,y2);
