DYgraphs get data from .csv format apart from writing to rrd I also write
to few .csv files. You put them in /www
data_s=`date +"%Y/%m/%d %H:%M"`
echo "$data_s,${temp[2]},${temp[3]},${temp[5]},${temp[8]}" >>
/www/dane1.csv2
(csv2 extension is because browser/server was giving cached version if the
extension was .csv)
and the file looks like this
data,dwor,t1,t2,t3,t4,t5,t6,t7,t8

Rrd was to complicated for me to set it up and record data from whole
year.Csv is much easier and when I finally master rrd I can feed it with
.csv data.
