[rrd-users] issues on graphing 1 year graph

[Neil]

Hey guys, 

This is how I created my rrd file. 

rrdtool create ping_on_deb.rrd -s 60
DS:minrtt:GAUGE:600:0:U
DS:maxrtt:GAUGE:600:0:U
DS:avgrtt:GAUGE:600:0:U
RRA:AVERAGE:0.5:1:483840
RRA:MIN:0.5:1440:1
RRA:MAX:0.5:1440:1
RRA:MIN:0.5:10080:1
RRA:MAX:0.5:10080:1
RRA:MIN:0.5:40320:1
RRA:MAX:0.5:40320:1
RRA:MIN:0.5:483840:1
RRA:MAX:0.5:483840:1 

I am just wondering why on my 1 year graph, values are becoming smaller. 

Here is my script that creates the drawing. 

#!/bin/sh 

HOSTNAME=$1
PUSHEDTIME=$2
SUBJECT=$3 

RRDB=/usr/local/nagios/rrd/ping_on_$1.rrd 

NOW=`date +%s`
ONE_HOUR_AGO=$(($NOW-3600))
ONE_DAY_AGO=$(($NOW-86400))
ONE_WEEK_AGO=$(($NOW-604800))
ONE_MONTH_AGO=$(($NOW-2419200))
ONE_YEAR_AGO=$(($NOW-29030400))
TIMESTAMP="Generated on `date`" 

function draw_graphic()
{
       rrdtool graph $1 -s $2 -e $3 -a PNG \
       -t "$SUBJECT, $4" -w 520 -h 160 \
