I doubt that there's an easy way to do this. You could delete all the
default x-tick labels and then use your own with the text command. You'd
have to find the coordinates so that they will be placed where you want
them.

15.1.3 Plot Annotations
-----------------------

You can add titles, axis labels, legends, and arbitrary text to an
existing plot.  For example,

     x = -10:0.1:10;
     plot (x, sin (x));
     title ("sin(x) for x = -10:0.1:10");
     xlabel ("x");
     ylabel ("sin (x)");
     text (pi, 0.7, "arbitrary text");
     legend ("sin (x)");
