Empty plot

[John B. Thoo]

Hi.  I'm sorry if this is a FAQ, but I haven't been able to find an answer.

I'm using Octave 3.2.3 on Mac OS X 10.6.4 in X11.  When I try to plot, I get an 
empty plot window and this:

octave-3.2.3:1> getenv ("GNUTERM")
ans = x11
octave-3.2.3:2> x = 0:0.1:pi;
octave-3.2.3:3> plot (x, sin(x))
octave-3.2.3:4> 
gnuplot> set palette file "-" binary record=64 using 1:2:3:4;
                                                            ^
         line 0: Gray scale not sorted in gradient.


octave-3.2.3:4>

When I start gnuplot on its own, I see that I have Version 4.2 patchlevel 5.

Any help would be appreciated.  Thanks.

---John.
