I am trying to plot labels on an xy type chart that are in a 3rd column and
not in the x or y chart. Can it be done? Sample below

Date Value Identifier
1/1/2008 3.06 ABC
2/1/2008 3.10 ABD
2/12/2008 3.08 ABE

Here i would be plotting Value against Date but would like to add labels to
the chart values with the Identifier(ie AB?) and not the value.
Thanks Steve
