VBARPARM also can do that.

proc sgplot data=Binom;
vbarparm category=j response=Binomial/ barwidth=1;
series x=t y=Normal / lineattrs=GraphData2(thickness=2);
inset "n = &n" "p = &p" "q = %sysevalf(1-&p)"
"(*ESC*){unicode mu} = np = &mu" /* use Greek letters */
"(*ESC*){unicode sigma} = sqrt(npq) = &sigma" /
position=topright border;
yaxis label="Probability";
xaxis label="x" integer type=linear; /* force TYPE=LINEAR */
run;
