Here is how I make a stacked ladder plot:

Unfortunately, you have to fool around with POSITION,
I think. What you could do, to make this easy on yourself,
is something like this:
Window, XSize=300, YSize=600 ; Window for plot.
p = Aspect(3.0) ; normalized coordinates for 3/1 plot ratio
p1 = p[1]
len = (p[3] - p[1]) / 3
p2 = p1 + len
p3 = p1 + (2*len)
p4 = p[2]
Now p1 through p4 are the Y values you need (in normalized
coordinates) for the three equal-area plots. p[0] and p[2]
are the x coordinates.
Cheers,
David
