I found it. Select a chart then the layout tab of the Chart Tools
ribbon, in the upper left hand corner of the ribbon there is a drop
down to select the different areas of the chart and the individual
data serieses.

I have one data series that is buried in the floor of a chart. I want

the floor. *I looked around on the ribbon but cannot find it.
any ideas?
