Is it possible that the two scales are such that one series is on top of the
other?
Try formatting one y-axis and change the value of Min.

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).
