Ok, here is what I have so far.
$rrd create file.rrd --step 1 DS:on:ABSOLUTE:0:900:0:2500 RRA:AVERAGE:0.5:1:9600
I populated the data
now, when I try to graph this data its all in different scales.
I am doing,
$rrd graph --start -2h --end -1h graph.png DEF:on=file.rrd:on:AVERAGE
What is the best way to graph this data?
