Just FYI, that isn't quite correct.  "n" increases with each plot in the
graph.  So if you say 
   plot sin(x),cos(x),'foo.dat','baz.dat'
these are plot_1, plot_2, plot_3, and plot_4.

Multiplot is a whole separate issue, currently broken.
I suppose we will have to come up with a revise scheme to handle it.

This isn't quite correct either, at least for me running firefox here.
Each plot has a title, and it pops up in a little box whenever the 
mouse is over that plot.   As you point out, the title of the first
plot also is displayed in the top window bar.  But I think that may
be a firefox bug/idiosyncracy.  Opera and Konqueror display the 
filename instead.  I don't mind adding something to make firefox
display a different title, but so far I have not figured out how :-(
