I think I would drop the CONTINUE keyword and just draw
from the last point to this point:

pro testPlots
arrayT = fltarr(11)
arrayX = fltarr(11)
arrayY = fltarr(11)
window, 1
plot,[0,10],[-10,10], /NoData
x1 = !X & y1 = !Y & p1 = !P
window,2
plot,[0,10],[-10,10], /NoData
x2 = !X & y2 = !Y & p2 = !P
for I=1, 10 Do begin
arrayY[I] = cos(I+1)
arrayX[I] = sin(I+1)
arrayT[I] = I
wset, 1
!X = x1 & !Y = y1 & !P = p1
plots,[arrayT[i-1], arrayT[I]], $
[arrayX[i-1], arrayX[I]]
wset, 2
!X = x2 & !Y = y2 & !P = p2
print, [arrayY[i-1], arrayY[I]]
plots,[arrayT[i-1], arrayT[I]], $
[arrayY[i-1], arrayY[I]]

endfor
end

This works perfectly, as far as I can tell.

Cheers,

David
