GNUPloter's...

	From time to time I have come across the need to generate graphics
constructs in a plot.  Normally this comes in the form of a line or a
text block.  These are well established in gnuplot currently.  Sometimes
I have needed to create a shaded region behind the data to help
illuminate it.  I have hacked it together to work somewhat, but it is
what it is, a hack.  I have included a small sample of what I mean.  It
would be nice if there were commands that allowed it directly.  for
instance.

  set box graph 0,0 to graph .5,1 ft 1

where ft would be the fill type.  possibly you could have a syntax that
allows you to specify the fill color and transparency.  There could also
be one for an arc.

  set arc graph .5,.5 graph .5 0 180 lt 1

This would make an arc in the middle of the plot like the top of a
circle with radius graph .5.  Just some ideas.  I looked at the patches
some time back to see if anything had been done for this but came up
empty handed.  Sure you can simulate all these by some sort of a
function but it would be better for the end user if he or she could just
say put a box here.
