myself 2 minutes ago. I think the extreme tiredness from antibiotics for a
tooth abscess are affecting my thinking today. Thanks again for your help.

Thanks for confirming David, but I could not see how to achieve it. I did
try
myself, and scanned through the Help topics but without success. It is
easy
to add extra observations in the same curve, but could you please guide me
briefly on extra data series. Thanks in anticipation.
