[rrd-users] Showing a longer timeframe on a graph

I'm using Cacti as a front end to RRD.

I've made a new RRA definition for 5 minute average, which rather than
keeping only 600 rows, keeps 8640 rows (the objective being to retain 30
days worth of data at a 5 minute resolution).

I would have thought that by specifying a start to rrdgraph that was say 2
weeks into the past, up until 300 seconds ago (one polling interval), would
have generated a graph that showed two weeks of data at the 5 minute
resolution, however this is pretty much exactly how Cacti is calling
rrdgraph to display a weekly graph at a 30 minute resolution.

So how can I use rrdgraph to get a "wider" graph, where no consolidation
