Re: problem with gnuplot/aquaterm invocation from /usr/local version of octave.

[Vic Norton]

I am using GNU Octave, version 2.9.9 (from High Performance  
Computing), and gnuplot, version 4.2, on Mac OS X 10.4.10 (PPC). I  
just ran the following test script from BBEdit:

   #!/usr/local/bin/octave

   ## test2.m

   plot (rand(100,1))

The plot came up perfectly in aquaterm. In fact I got a different  
plot in a different aquaterm window every time I ran the script.

Apparently the problem is not universal.

Regards,

Vic
