Change Rotation of category axis in XL 2007.
 

Using VBA I want to change the alignment of the text of the Category axis to
"Rotate all text 270o".
Manually: right click chart category axis, select "Format Axis", select
Alignment, Click Text Direction and scroll to "Rotate all text 270o, click
close. I cannot figure out how to do this in VBA. Please advise.
Thanks.
