I built for my company a template for top-level statistical & financial
reporting to client Boards of Directors. The final output has 6 graphs, 2
'line' and 4 'radar'. I originally built the template on Excel 03, although
most clients now use it on Excel 07.
One of the clients has a very odd problem. When she uses the workbook in
Excel 03, one of the line graph's time axes -- the X axis -- shows a
different time range than the other. Both graphs pull the data for the X
axis from the same range of cells. When she (or I) opens the workbook on a
different computer using Excel 07, both line graphs function normally and
both show the same correct time span on the X axis.

What might be causing this bizarre behavior? She uses XPPro.

Thanks in advance.
