I have made so many charts (more than 200) in different worksheets in EXCEL. The X axis in each chart is the time originally from 1984/1/1 to 2000/1/1. Now I want to change all the X axis in all the worksheets from 1990/1/1 to 2000/1/1. I know I can change one by one, but it is just so boring to change the same thing one by one. I am wondering whether someone can tell me a way to make it simple to operate.
Thanks in advance.
