scaling plots lengths
 

Hi all
I want to know if it is posible to set the size (length in cm) of the
x-y-axes in excel97. I know how to set the scale by right clicking on the
axis but i want to scale 2 seperate plots to be identical ie 1cm =1 unit so
plots are directly comparable. This sounds like an obvious thing to want to
do but it is either very well hiden or tricky to do in excel.
Anyone know how to do this?

Cheers

Chris
