Not that I've seen.  But it now occurs to me that you can do this
trivially in the current CVS version by using object type "circle"
with transparent fill:

   set size square
   unset border
   unset xtics
   unset ytics
   set xrange [-2:2]
   set yrange [-2:2]

   set angles degrees
   set object 1 circle at cos(60),  sin(60)  size 1.1 fc rgb "cyan"
   set object 2 circle at cos(180), sin(180) size 1.1 fc rgb "magenta"
   set object 3 circle at cos(300), sin(300) size 1.1 fc rgb "yellow"

   set object 1 fillstyle transparent solid 0.25 noborder
   set object 2 fillstyle transparent solid 0.25 noborder
   set object 3 fillstyle transparent solid 0.25 noborder

   plot -4 notitle  # won't appear on plot
