Well, its name isn't Helvetica--which is partly why I inquired about unix.  ("Triumvirate" is an interesting choice of name.)  We've been refering to Helvetica, because it is so common, but in GPL parlance, there is no "Helvetica", as this article would lead to believe.  However, I do see in the font list for OpenOfficeWriter that there is a "Helvetica", but the default font is "Nimbus Roman No9 L".

Going a little further, I can select the font properties for gnome.  "Helvetica" is not in the list, but "Nimbus Sans L" is.  (So, I don't know where OpenOffice gets its "Helvetica" from, but it does in fact look like Helvetica and not some similitude.)

As far as gnuplot, another issue is that main developers have historically not been Windows users (everything but).  So, Helvetica support hasn't been a priority, and neither has compatibility across platforms, I suspect.

What Octave should probably be doing behind the scenes is mapping all names to equivalent names which are system dependent.  For example, "Helvetica" would get mapped to "Helvetica" on Windows, "NimbusSansL" on unix.  (Actually, it should probably be mapped to "NimbusSansL" in both cases since that font is GPL.)
