I'm using OS X 10.4.7 on a G4 processor. I installed the octave-bin.tar.gz package from http://hpc.sourceforge.net/ and followed the instructions. Following that I installed AquaTerm 1.0 and then Gnuplot 4.0.0. From terminal /usr/local/bin/gnuplot I am able to set 'set term aqua' (without the quotations) and then plot to AquaTerm with Gnuplot. However, from Octave I am unable to plot. The command plot (x) , where x is previously defined, does not plot and does not give an error message. If I use the command gset terminal aqua I am able to plot but apparently this command is being discontinued.
From what I've read in the message archives it appears that I will need to create .gnuplotrc and .bashrc files in my home directory to allow octave to pipe instructions to gnuplot. Specific instructions on how to do this are much appreciated.
