Again something different (and not nice !!!) with 2007 (it's amazing how much
is necessary to have your all code doing the same thing as with previous
versions) :

Lets take a sheet with column A empty. add text in the first 5 rows of
column B. Select A1. Then do

ActiveWorkbook.Charts.Add

This will add a chartsheet with an ugly series that you never asked for.

Do the same with the previous versions. You will have an empty chart,
waiting for your instructions to add series.
