(1) Use label
I think the most simple way is usage of empty label.
set label at xPos, yPos, zPos "" point pointtype 7 pointsize 2
(2) Use standard input "-"
(3) Use special filename "+":
see an another example (it is convenient for discrete sampling)
(4) Use object
set object circle at first -5,5 radius char 0.5 \
fillstyle empty border lc rgb '#aa1100' lw 2
set object circle at graph 0.5,0.9 radius char 1 arc [0:-90] \
fillcolor rgb 'red' fillstyle solid noborder
set object rectangle at screen 0.6, 0.2 size char 1, char 0.6 \
fillcolor rgb 'blue' fillstyle solid border lt 2 lw 2
