I'm using EXCEL 2003 so I hope this is consistent.

In order to have a secondary Y axis, you need to have a minimum of 2 series.
Once the 2 series are on the graph, doubleclick on the series you want on
the secondary axis. You should see the Format Data Series menu. You then
can select the Axis menu and select Secondary axis on that menu.

I am creating a graph in Excel 2002 with 2 data series (bone mets and no
bone
mets). I need to add a second y-axis to the graph, but when I follow the
excel Help directions, it removes one of my data series from the graph
(ie,
it can no longer be viewed).
