Hmm. There`s something i realy can`t get right here. Here`s the "testing" I
have done (some right from the manual).

First i create the *.rrd like this:

	rrdtool create all.rrd -s 300 \
		DS:a:GAUGE:600:-100:100 \
		RRA:AVERAGE:0.5:1:200 \
		RRA:MIN:0.5:12:200 \
		RRA:MAX:0.5:12:200 \
		RRA:AVERAGE:0.5:12:200

Then i am trying to populate the database with lines like this:

	rrdtool update all.rrd N:10
	rrdtool update all.rrd N:20
	rrdtool update all.rrd N:30
	rrdtool update all.rrd N:40
	rrdtool update all.rrd N:50
	rrdtool update all.rrd N:40
	rrdtool update all.rrd N:30
	rrdtool update all.rrd N:20
	rrdtool update all.rrd N:10
	rrdtool update all.rrd N:0
	rrdtool update all.rrd N:-10
	rrdtool update all.rrd N:-20
	rrdtool update all.rrd N:-30
	rrdtool update all.rrd N:-40
	rrdtool update all.rrd N:-50

This would give me some negative values to (right?). But! When i try to
create an graph (*.gif) from this data, it seems like there`s no data in the
rrd. Also: when i try to do an "rrdtool fetch all.rrd AVERAGE" i just get
lines like this:

	996973200:  NaN
	996976800:  NaN
	996980400:  NaN
	996984000:  NaN
	and so on...

I can`t se where i`m doing the wront turn here.. :(
