Excel 2002(XP)sp3 running on XP Pro.

Chart wizard appears to work until rendering the chart on the sheet.
The resulting chart is drawn incorrectly. Line and Bar render only a
thin vertical line without any data. Preview mode during the chart
works ok. Pie charts render as a tiny dot vs a large circle.

I have tried uninstalling Excel and re-installing. Insert Graph OLE
object works fine. Can't re-install sp3 as it's already been installed.

Would it help to completely remove Office as when I re-installed Excel
all settigns were still in place, like tool bars and customizations.

Any ideas on how to "reset" chart wizard defaults?

Thanks!
