draw the arc as a function:
set parametric
set xrange [-1.1:1.1]
set yrange [-1.1:1.1]
set trange [0:1]
set size square
deg2rad(x)=x/180.*pi
set arrow 1 from
0.5*sin(deg2rad(45.+90.))+0.001,0.5*cos(deg2rad(45.+90.))+0.001 \
to 0.5*sin(deg2rad(45.+90.))-0.001,0.5*cos(deg2rad(45.+90.))-0.001 size
0.1,10
#1st we draw a full circle, then an arc from 45° to 45°+90°
plot sin(2.*pi*t),cos(2.*pi*t), \
0.5*sin(t*deg2rad(90.)+deg2rad(45.)),0.5*cos(t*deg2rad(90.)+deg2rad(45.))
