I guess that you are using redhat.

Origin of your trouble perhaps exist in the gnuplot but not octave

Can you execute gnuplot from the shell prompt and see like the below ?

$gnuplot

The above is a snapshot of gnuplot 4.3 (cvs) on cygwin.

The version of gnuplot is not related with your trouble.

Do you see the following?   

Terminal type set to 'x11'

If you can see the above your gnuplot perhaps is broken.
