Basic question about resizing charts

[Vintage79]

Hello all,

I have charts in different files. Some of them change shape and size when I change the shjape and size of the Excel window. Others are like a fixed object on the sheet and do not move at all. But all of them are on their own, filling a whole sheet. I didn't embed them onto a sheet that has other cells.

Does anyone know why this happens?


Thanks a lot!

PS I am using Excel 2000

I thought this would be an easy one.
