Yes, that small window (what I called the "paper") is where gv puts the 
interpretted PostScript.  The parent window underneath is the one which 
will allow gnuplot_x11 to write to it.  As I say, it is just a 
proof-of-concept that gnuplot_x11 can write to an outside window. 
 Nothing more.

I've never worked with tcl/tk, but after poking around a bit on my 
RedHat distribution I think I'm catching on.  To launch tcl is "tcl", 
that's easy enough.  But to get the X extensions tk interpretted is 
another matter.  I see "tclx" and "tk" are extensions.  Is the 
interpretter for the tk portion of all this something called "wish" or 
"wishx"?  [There is all kinds of documentation on tcl/tk, but nothing 
telling you what command to start it.]

So a "frame" seems like a fundamental thing in "wish", but that isn't 
necessarily the same thing as an X frame.  My guess is that "frame" is a 
simple tk concept of a place to position buttons, dials, etc.  Probably 
not the sort of thing that allows gnuplot_x11 to put a plot there.

"canvas" sounds more like a versatile window in which to put graphical 
stuff.  There is a demo as part of tk called "widgets", and in there is 
a demo for images.  I tried hooking gnuplot_x11 to one of those windows. 
 Unfortunately, it causes the tk demo to crash.

Someone with a clearer understanding of X and the types of X windows or 
configuration that works with what gnuplot_x11 is attempting to do might 
be able to help.
