It looks as though what happened is that I installed xcas on my machine,
which automatically added a patch to gnuplot.  I am in the process of
figuring out what step to take now:

-removing and reinstalling gnuplot does nothing
    

I suspect that xcas installs gnuplot into /usr/local/bin
and you are re-installing gnuplot to /usr/bin

  

Okay, it looks like this might be the case.

You can set variable gnuplot_binary (in .octaverc)
to point to the unpatched gnuplot (/usr/bin/gnuplot).
I.e. in the file .octaverc add the line:

Just out of curiosity, is my .octaverc file supposed to be in my default directory (/home/me)?  I didn't see one there but created one and it seems to load up when I start octave.  I was just wondering if it is created by default or not.

gnuplot_binary="/usr/bin/gnuplot "

  

Okay, done.  Now when I start up octave, here is what happens:

gnuplot_binary = /usr/bin/gnuplot
octave:1> x = 0:10;
octave:2> plot(x);
sh: line 1: /usr/bin/gnuplot : No such file or directory
warning: in /usr/local/share/octave/2.9.3/m/plot/__plt__.m near line 181, column 3:
warning: connection to external plotter (pid = 4408) lost --
warning: please try your plot command(s) again
warning: broken pipe -- some output may be lost
sh: line 1: /usr/bin/gnuplot : No such file or directory
warning: broken pipe -- some output may be lost

I'm not sure why this would happen, because I KNOW that /usr/bin/gnuplot is there.  Do I need to possibly remove the /usr/local/bin/gnuplot, and if so, how do I do that?  Thanks for the help!

Oh, one more thing:  Is everything I have in my .octaverc file going to appear on startup?  Just wondering.
