Thanks!
Is that something I can build into the query? To do the arithmetics and be able
to feed an arbitrary start/end into the query?
Such as
rrdtool graph /usr/share/nginx/www/test.png -s "20130101" -e "now"
DEF:ds0=/opt/Krokopool/RRDDatabases/Styrning_Varmare.rrd:Styrning_Varmare:AVERAGE
VDEF:ds1=ds0,AVERAGE PRINT:ds1:%20.2lf%s
0x0
123.86m
