Hello,
I'm collecting data from my weather station and keep the data in a rrd. I've consolidated values over the year for minimum, maximum and average temperature for each day of the year. I would like to present the number of days that meet some criteria, i.e. "Number of hot day (Max Temp > 30°C)" .
I've tried with rrdtool graph temps-2016-2103test.png -s 20160701 -e start+1m \ -w 1200 -h 300 \ --upper-limit 40 --lower-limit -15 \ --title "Temperatur 2016 Test" \ DEF:tempmins9=/var/rrd/weather.rrd:temps9:MIN:step=1 \ DEF:tempmaxs9=/var/rrd/weather.rrd:temps9:MAX:step=1 \ DEF:temps9=/var/rrd/weather.rrd:temps9:AVERAGE \ CDEF:hotday=tempmaxs9,30,GE \ VDEF:sumhotdays=hotday,TOTAL \ CDEF:tempranges9=tempmaxs9,tempmins9,- \ LINE1:tempmins9#00C000 \ AREA:tempranges9#00F000::STACK \ LINE1:tempmaxs9#00C000 \ LINE2:temps9#00C000:Aussen \ LINE2:hotday#C00000:Hotday \ GPRINT:sumhotdays:"total %3.10lf %s"But the result is weird... the line for hotdays is working, showing 1's for all days above 30, but the total is 1.296000 M, not 14...
kind regards Alexander -- liebe Grüße Alexander Topolanek http://www.bienenhonig.cc
