Thank you so much! Have been using Excel for years and never tried that! Years! After your suggestion I opened up a table in Excel, highlighted the column labels as well as the the row labels and PRESTO! series labels in the legend.
You have made my remaining years easier!

Probably a dumb question: how can I label several series in a line graph as a group, rather than one at a time, as is required in the "select data" dialogue?
