Thanks! For some reason I missed the axis function of NG.

x = FINDGEN(100)
theta = x/5
curve = SIN(x/5) / EXP(x/50)
p1=plot(x,curve, AXIS_STYLE=1)
p2=plot(x,theta,/
current,COLOR='ff00'xl,YCOLOR='ff00'xl,YTEXTPOS=1,YLOG=1,
AXIS_STYLE=0)
px = axis(TARGET=p2,'Y', LOCATION=[x[-1],theta[0]], /DATA, TEXTPOS=1)
comments:
AXIS_STYLE=1 suppresses the right-hand side axis in first plot
AXIS_STYLE=0 suppresses all axes in second plot
the NG axis function draws an axis at the location you like.
TARGET allows the axis to be attached to the right plotting object.
