I, too, am suffering this problem. I have a three-series line chart and the
formatting for two of the series keeps reverting to unusable formats. I fix
them, save, close, reopen, and they're back to being unusable.

I even tried saving a custom chart type after fixing everything, and that
caused them to revert to the unusable formats.

I am using Office 2003.

I've been using Excel for many years and this is the first time I've ever
seen this problem.

If it's any help, my chart is a line chart with 3 data series, 2 of which
are on the primary X/Y axes, and the other is on secondary X/Y axes.

The first series (on the primary axis) works fine and holds all formats.
It's the 2nd and 3rd series (2nd on the primary and the one on the secondary)
that fail to hold formats. They re-check their "Linked to Source" options on
the Number tab (they shouldn't), they revert font size to 26.5 pt (should be
8) and remove all colors/borders/fills I apply.

This is very frustrating.

I am having the same problem with Excel 2003. My problem only effects the
newest data on my chart. The chart plots data per quarter for the last 3
years, but only the data from the current year reverts back to the default
format (Black Text, Arial, 10pt, Normal) I can change it to match the older
data and save, then reopen and it's back to the default format. Please help,
this report has very high visibility in my company.

Thanks, Rick

Excel 2007. I am trying to change the font size of data labels on a line
chart. Also changing the color of the lines. After making the changes and
saving the spreadsheet, if I close and reopen the sheet, the data labels and
line colors have reverted to default size, fonts, and color.

I need to put these charts in a powerpoint. When copying into power point
all formats also revert to default. Using Powerpoint 2007. Doesn't matter
what type of paste either. paste, paste link, or paste special. png, jpg, or
metafile all revert to default once pasted into powerpoint.

Presentation is Monday, Please help!!!
