[rrd-users] Controlling time interval on graphing

[robstar]

I recently started using RRD and it's awesome.... but I can't get it to plot
more than the last 24hrs of data...

here is my setup:

rrdtool create temperature.rrd --step 60 \
  DS:temp:GAUGE:300:-273:5000 \
  RRA:AVERAGE:0.5:1:1440 \
  RRA:MIN:0.5:60:2400 \
  RRA:MAX:0.5:60:2400 \
  RRA:AVERAGE:0.5:60:2400

doesn't this store more than 1 day of data for me?

If I leave out the --start/end I get the last 24hrs...  and here's what I
use to generate the graph for today:

rrdtool graph temp.png DEF:t=/var/www/eheat/rrd/temperature.rrd:temp:AVERAGE
-w 600 -h 300 --start 1242878400 --end 1242964799

how can I get the last week?  last month?  any interval I want?  anything
but the string above generates a blank graph!!

Thanks for your help.
