[rrd-users] Generated graph does not show the pdp at exact y-axis point

[Shedi Shedi]

Hi,

i'm running the following set of commands. When the graph is generated PDP
whose value is 6 is shown on Y-axis at point 5.5 and not 6.


rrdtool create msgmgr_basic.rrd --start 1188287728 --step 60
DS:recdsuccess:GAUGE:120:U:U RRA:LAST:0.5:1:1440
rrdtool update msgmgr_basic.rrd 1188287788:1
rrdtool update msgmgr_basic.rrd 1188287848:2
rrdtool update msgmgr_basic.rrd 1188287908:3
rrdtool update msgmgr_basic.rrd 1188287968:4
rrdtool update msgmgr_basic.rrd 1188288028:5
rrdtool update msgmgr_basic.rrd 1188288088:6
rrdtool update msgmgr_basic.rrd 1188288148:2
rrdtool update msgmgr_basic.rrd 1188288208:2
rrdtool update msgmgr_basic.rrd 1188288268:1
rrdtool graph msgmgr_basicrecd_stats.png --start 1188287728 --end 1188288268
--watermark ivems --alt-autoscale --title "iVEMS-Message Manager [Received
Messages] " --vertical-label "No. of Messages"
DEF:recd_success=msgmgr_basic.rrd:recdsuccess:LAST
"LINE2:recd_success#0033FF:Received Success"


I'm new to rrdtool and not sure what i'm doing wrong.Any hints!

regards,
shedis
