You'll need to save the gnuplot commands and edit them yourself.

What does the "jsdir './js/' name 'file.js'" part do ?

Is this something that should be included by default ?

By default the .js and .css files are set to "/tmp/gnuplot-some-dir/etc", requiring the html to be edited every time.  The jsdir parameter allows you to set the _javascript_ directory, in my case "./js/" .

The "name" parameter outputs the canvas as a _javascript_ file which can then be included in a more complex html file.  This will allow us to just modify and include the canvas instead of re-editing the html file every time.   This change alone, would allow us to run the Octave commands and then just reload the html to view an interactive plot instead of modifying the octave output to gnuplot every time.
