You can't do it the way you're hoping to.  Although you can have
two lines present in a single graph, you can't have two scales.
However, you CAN divide your y axis values for the second graph
by 25 and then use PRINT to place your own labels for the second
chart by hand.  This is definitely a hack, but it may work for you.
