Hi Ben, I'm using Octave 3.2.3 on Debian Squeeze.
See the graphs attached.

- standard_output.jpg = Standard output using semilogx;
- with_xtick.jpg = After use "set (gca, "xtick", [20, 30...]"
- with_xtick_label.jpg = After use "set (gca, "xticklabel", ["20", "30"...]

How you can see, the labels is not ok.

Renato
