I had some trouble running your script (it got scambled via email, I think).  
I've attached a corrected one for anyone interested.

If you are running Octave 3.6.x, then I recommend you try using the fltk 
graphics toolkit instead of gnuplot.  The fltk toolkit will modify the axes 
widths and heights to avoid having the titles, and axes labels from over 
lapping.  Just run the commands below and then run your script.

        close all
        graphics_toolkit fltk
