RTFM ?

What did you tell rrd to store in your database ? Normally, you store 
a short time at high resolution, a bit longer at lower resolution, 
longer still at even lower resolution. If you've only stored a couple 
of months of high-res data then there's no way you can plot longer 
graphs at full resolution.

The other factor is to make sure your end time is a multiple of the 
stored step size.
