Name only one bar in a diagram

Hei!
Have another problem too. I have a list in Excel with 2 rows. One with names and one with data. The list has 30 rows. I want to create 30 diagrams with all data in bu only showing the name for one of the persons. The other bars should be "nonamed". And is it possible to create all 30 diagrams in "one click"?
Thanks for all tips you might have,

Jonny
