using a Macro Button to go either forward or backward on my graph

[oasalako1]

Hi All,

Please I need help on my attached spreadsheet. I need my Graph to always show me only 12 Months as we progress the year in 2014 as seen in my example.
E.g (Feb-13 to Jan-14) or (Mar-13 to Feb-14) etc but by using a Macro Button to go either forward or backward on the Graph.

Your help would be appreciated.

Regards
Olu
