Do you mean by setting the setting axis globally, the figure will have fixed properties for all functions?
If so:
set(0, 'defaultaxesxlim', [range]);
set(0, 'defaultaxesylim', [range]);
If you mean to set axis for all the subplots, you can use the function linkaxes()
h1 = subplot(1,2,1);
hold on
plot('')
h2 = subplot(1,2,2);
hold on
plot('')
linkaxes([h1, h2], 'x')
Something like this.
