2003 charts don't format to page size in 2007. any suggestions
 

I have numerous charts created in Excel 2003 that are formatted to print very
legibly on 8-1/2 x 11. Excel 2007 does not seem to make any proportional
adjustments base on paper size, resulting in a long flat chart that is not
legible because the print is too small. Any suggestions on how to modify the
ratios. Clicking on print options "print on 1 page high by 1 page wide" has
no effect. the height and width ratios do not change at all as they did in
2003.
