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?
A few ways:
1. Select your data and labels prior to making the chart, then Excel will do it for you
2. Use VBA or an addin
3. Do it manually, your present method
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.
