Resizing Graphs

Hi, I have an excel file with a number of graphs. Sometimes when I open the file the charts resize and the layout is all messed up - can anyone provide advice on how I can have these permanently fixed in place.

Any help would be greatly appreciated.

Thanks,
Paudie

Well, this is me shooting from the hip, but if I had to guess some of the bits of the charts--plot area maybe?--have retained auto-sizing while others are retaining manual settings.

Anyway, if you don't mind posting a copy of your spreadsheet, that will make it 100x easier to diagnose your problem.
