Hello all :
I'm having a problem with rrdtool runing it under windows platform.
(or I'm trying to use it incorectly ...)
I'm trying to use it's graphing capabilities to graph the spead of a
machine.
using those values I'm trying to produce the two hours graph :
Date : 12/5/2002 1:26:45 PM Date in UX : 1039112805 Speed : 26.7
Date : 12/5/2002 1:35:43 PM Date in UX : 1039113343 Speed : 25.5
Date : 12/5/2002 1:50:13 PM Date in UX : 1039114213 Speed : 27.5
Date : 12/5/2002 2:25:12 PM Date in UX : 1039116312 Speed : 29.5
Date : 12/5/2002 2:35:43 PM Date in UX : 1039116943 Speed : 28.8
Date : 12/5/2002 2:58:10 PM Date in UX : 1039118290 Speed : 26.6
Date : 12/5/2002 2:58:27 PM Date in UX : 1039118307 Speed : 0
Date : 12/5/2002 3:16:12 PM Date in UX : 1039119372 Speed : 29.3
Date : 12/5/2002 3:26:45 PM Date in UX : 1039120005 Speed : 29.3

using those commands :
rrdtool create 2.rrd --step 60 --start 1039112745 DS:sp:GAUGE:7200:0:80 RRA:MAX:0.5:1:122
- allocate 120 sample spaces every 60 sec  in RRA I have tried all
MAX, MIN, LAST , AVERAGE ... You name it ....
rrdtool update 2.rrd 1039112805:26.7 1039113343:25.5 1039114213:27.5
1039116312:29.5 1039116943:28.8 1039118290:26.6 1039118307:0
1039119372:29.3 1039120005:29.3
- updating it with values
rrdtool graph 2.gif --start 1039112805 --end 1039120005 --width 600
--height 220 --title="machine spead test" DEF:cel=2.rrd:sp:MAX
LINE1:cel#00aa00:"some machine spead"
- graph the resoults

By dumping the data to XML it shows the following :

Which is not what I expect to happen because at 13:32:00 my machine
was still running at the spead of 26.7 (untill it changed to 25.5 at
1:35:43).
In short it looks to me that if there are some samples missing rrdtool
fills the blanks backwards in time with the last value.
I wouldlike to know how to achive the oposite ... if the samples are
missing fill the blanks with the previous value.
There must be a simple fix for my problem ... 
The machine only logs the spead change when it happens ...
I have 'google' the problem for the last 2 days and .... I must be
very stupid and dumm because I could not find the way arround it
( with the exception of actualy creating a record for every sample
allocation).
I would appriciate any pointers.
