display last 12 months

HI,

I have a requirement of displaying the data of last 12 months, month wise. If i give an input as Dec 2009, it should diplay data from Jan 2009 to Dec 2009 separately as follows

Jan 2009

Feb 2009

March 2009

---

---

Dec 2009.

The above can be achieved by creating 12 selections and changing the offset. But i want to know is there any better way of doing?

Regards.
