Chart plot area aspect ratios different?

[iszlq]

I have a number of charts in the same workbook. Some of the charts have a different size plot area. Not the chart itself, but the white "pasteboard" that is behind it. Because I ultimately output all of my charts to pdf's and then to gifs (in Photoshop) this change is aspect ratio is messing me up. Does anyone know how Excel "decides" what shape the pasteboard is going to be? Is there a way to set it?

Thanks,

Ah I found the problem... Apparently my margins were set differently in Page Setup. I never set any margins, so I'm suspecting that this is because the charts were created in different versions of Excel.
