Hey

xx=[0 1 2 3 4]
yy=[0.0000001 1.0000002 2.0000003 3.0000005 4.0000006]
figure
plot(xx,yy,'-*')

You create a zoom object and set the callback function for it to decide the appropriate resolution for ticks and set() the xtick positions and xticklabel strings.
You will probably also want to rotate the labels so they do not overlap with each other. Rotating the labels is a bit of a messy process before R2014b but from R2014b onward is easier. I think it likely there is something in the File Exchange that would do label rotation on your behalf.
