[rrd-users] Graphing average temperatures

[Petteri Matilainen]

How? I have

DEF:Inside=/var/digitemp/temperature.rrd:in:AVERAGE
LINE1:Inside#3333CC:"Inside"
GPRINT:Inside:AVERAGE:"\t%6.2lf °C" <- this is the average I want to plot

which give me the "ordinary" graph. If I have

VDEF:avg=Inside,AVERAGE
LINE1:avg#3333CC:"Average"

I get a straight horizontal line.
