You need more RRAs!
Right now you only store 999*$STEP seconds of data (why not 1000, btw? :)
so if $STEP = e.g. 30, that's enough for a graph of the last 8 hours
only.
Create additional RRAs, e.g.
RRA:AVERAGE:0.5:12:1000 RRA:MIN:0.5:12:1000 RRA:MAX:0.5:12:1000 and
RRA:AVERAGE:0.5:100:1000 RRA:MIN:0.5:100:1000 RRA:MAX:0.5:100:1000
(I think you get the idea :)
