interactive plotting functionality

[Ben Abbott]

Did you download Octave 3.0.3?

	http://sourceforge.net/project/showfiles.php?group_id=2888&package_id=237839

For this version of Octave you'll need gnuplot 4.2.3 or greater. You  
likely have more than one gnuplot on your mac. When you downloaded the  
octave.app.dmp from sourceforge it contained an "Extras" folder which  
contains "gnuplot-4.2.3-i386/ppc.dmg". If you installed this there  
should be a gnuplot.app in your Applications folder.

Do you have a gnuplot in our Applications folder?  and if so what is  
its version number?

My understanding is that  when the octave bundle you have is run it  
will look to see if a gnuplot exists in the path and then look for the  
gnuplot bundle in your Applications folder.

To determine if there is another gnuplot in your path, open a terminal  
window and type "which gnuplot". What I get is below,

	$ which gnuplot
	/sw/bin/gnuplot

To determine the version of this gnuplot, type

	$ gnuplot --version
	gnuplot 4.3 patchlevel 0

Does "which gnuplot" return anything? ... if so, what version?

I'm running the developer's version of gnuplot which I built by adding  
a local package to the Fink package management system. You're results  
will be different.

I suspect you have more than one gnuplot installed and that one is  
version 4.0 and the other 4.2.

Once it is determined where the 4.0 version resides, I recommend you  
update or uninstall it.
