Added Tomaz to the CC list since (I believe) he has worked on pivot 
chart and may have a fresher memory on this topic.

I myself have hard time remembering the detail around this plot area 
data source address requirements.  I do seem to think that there was 
some weird exception that "allowed" a regular name to be used as a data 
source especially when the data source is not from Calc document but is 
from the internal data provider...  But I wouldn't trust my own memory.
