What is excel? As far as I understand this, you have two variables (x and y)
with just a few categories. If so, you might try heavy jittering. Something
like
. graph y x, yline(0.5(1)4.5) xline(0.5(1)4.5) xlab(1(1)4) ylab(1(1)4) /*
*/ jitter(20) xscale(0,5) yscale(0,5)
(Fiddle around with the number in jitter. It can be between up to 30. -help
grtwoway- states that jitter(5) is already large)
