Excel 2k3 Graphs not appearing in 2k7.
 

In our company we have some users still using Excel 2k3 and most of
the newer users have already upgraded into Excel 2k7. One of the work
books that our accounting department uses will display all the graphs
in Excel 2k3 but when a user on Excel 2k7 opens the same workbook it
will not display the graphs.

Does anyone have any idea on why?
