I think you will need a column of data labels that could be placed on your
chart with one of these add-ins

Hello,
I am graphing a series of data in a bar format in excel. Some of the
entries have no data. Instead of interpolating, graphing zero, or just
leaving gaps, I'd like excel to put a "no data" or similar message in the
spot where a bar would otherwise be. (I can't have it shown as zero, as
there are legitimate zero entries as well.)

How do I do this? I am using excel 2003.
