;; I believe you are looking for the /noerase, and [xy]style keywords in
;; conjunction with the axis function

pro try_this
x = [ 0, 1, 2, 3, 4 ]
a = [ 50, 59, 46, 29, 30 ]
b = [ 728, 1061, 1382, 1620, 1630 ]
PLOT, x, a, yrange = [ 20, 150 ], ystyle = 8, XMARGIN=[ 10, 10 ], xstyle = 1
PLOT, x, b, yrange = [ 700, 1700 ], /NOERASE, ystyle = 4, $
xstyle = 1, XMARGIN=[ 10, 10 ]
axis, /YAXIS
end

See the manual for [xy]style graphics keyword and axis functions.

Hope this helps.
