[rrd-users] how correctly make speed graphics

[moose]

Hi everybody! 


For the first , I'm using Freebsd 8.1, perl-5.10.1_3 , rrdtool-1.4.5

I'm trying to make graphics of speed taking data from traffic and time
intervals

I create rrd data file  with this command

rrdtool create data.rrd --start 1306144107 \
DS:in_traf:ABSOLUTE:900:0:U \
DS:out_traf:ABSOLUTE:900:0:U \
DS:in_ex:ABSOLUTE:900:0:U \
DS:out_ex:ABSOLUTE:900:0:U \
RRA:AVERAGE:0.5:1:4800 \
RRA:AVERAGE:0.5:4:4800 \
RRA:AVERAGE:0.5:24:3000 \
RRA:AVERAGE:0.5:24:3000


then I'm using a script which updates data.rrd

the data look's like this:

1306141169:0:0:0:0
1306141289:9172384:282192:0:0
1306141345:16245755:404806:0:0
1306141353:0:0:0:0

1306142786:54646886:988551:0:0
1306142907:70056236:1241033:0:0
1306143027:85338085:1492768:0:0
1306143147:99724539:1767412:0:0
1306143267:113580324:2004315:0:0
1306143387:127187549:2234010:0:0
1306143507:140820894:2461959:0:0
1306143627:150649717:2666047:0:0
1306143747:155830409:2755337:0:0
1306143867:155830481:2755397:0:0
1306143987:155831017:2756897:0:0
1306144107:155832639:2758684:0:0

at the end I'm creating graphics with such command

rrdtool graphv graphic-daily_1.png \
-w500 \
-h100 \
-b 1024 \
--title Daily \
--start -12h \
--end now \
--imgformat PNG \
--interlace \
DEF:in_traf=data.rrd:in_traf:AVERAGE \
DEF:out_traf=data.rrd:out_traf:AVERAGE \
DEF:in_ex=data.rrd:in_ex:AVERAGE \
DEF:out_ex=data.rrd:out_ex:AVERAGE \
AREA:in_traf#00DD00:in_traf \
LINE1:out_traf#F15500:out_traf \
AREA:in_ex#FF0000:in_ex \
LINE1:out_ex#0561FA:out_ex

but it drowing wrong speed information

Could someone suggest what do or where's my fault?

Thanks
