Derrick,

Create a simple line chart as an example with the following data:

Ser1 Ser2
a 1 4
b 2 3
c 3 4

In the clart plot area, double-click on the series called "Ser2". It should
be the higher line of the two series. In the Format Data Series dialog box,
go to the Axis tab. Choose the option "Plot series on: Secondary axis".
