Are you using fltk or gnuplot as graphics_toolkit?
You could also add "-debug" to your print command (for example
print("testplot.ps","-debug") to see the gnuplot or fltk pipeline.
In the case of gnuplot you'll also find a octave-print-commands.log
which might help finding the problem (if it also exists with gnuplot).

Another way to find the problem is to save as ps or eps and run then gs
from the commandline without QUIET (perhaps there is also a verbose flag)

PS: I want to create a wiki page "debug plotting issues in octave",
would you like to help me?
