Andy,
Thanks very much. It was quick and easy, just 4 data entries and
a series name. I guess I should have figured that out for myself,
but I only use charts occasionally and have to relearn the
process each time. Thanks again.

Mike

Hi,

Use an additional data series to draw the line rather than a drawing

There are numerous examples of adding datum lines to charts here.
