I won't list all the changes for all the graphs, but I will list the old and then the new below for the yearly graph... # # Graph for temperature, Dalmore, Dunedin # -- YEAR # rrdtool graph /var/www/rrdtool/temperature-year.png \ DEF:in1=/var/www/rrdtool/temperature.rrd:internal:AVERAGE \ DEF:in2=/var/www/rrdtool/temperature.rrd:inside:AVERAGE \ DEF:out=/var/www/rrdtool/temperature.rrd:outside:AVERAGE \ VDEF:MaxIn1=in1,MAXIMUM \ VDEF:MinIn1=in1,MINIMUM \ VDEF:AvgIn1=in1,AVERAGE \ VDEF:CurrentIn1=in1,LAST \ VDEF:MaxIn2=in2,MAXIMUM \ VDEF:MinIn2=in2,MINIMUM \ VDEF:AvgIn2=in2,AVERAGE \ VDEF:CurrentIn2=in2,LAST \ VDEF:MaxOut=out,MAXIMUM \ VDEF:MinOut=out,MINIMUM \ VDEF:AvgOut=out,AVERAGE \ VDEF:CurrentOut=out,LAST \ COMMENT:"\t\t\tMax\t\t\t\t Min\t\t\t\t\t Average\t\t\t\tCurrent\n" \ AREA:in2#00FF00:"Inside" \ GPRINT:MaxIn2:"%8.2lf deg C" \ GPRINT:MinIn2:"\t\t%7.2lf deg C" \ GPRINT:AvgIn2:"\t\t\t%8.2lf deg C" \ GPRINT:CurrentIn2:"\t\t%8.2lf deg C\n" \ LINE1:out#FF0000:"Outside" \ GPRINT:MaxOut:"%7.2lf deg C" \ GPRINT:MinOut:"\t\t%7.2lf deg C" \ GPRINT:AvgOut:"\t\t\t%8.2lf deg C" \ GPRINT:CurrentOut:"\t\t%8.2lf deg C\n" \ --title "Temperature, Dalmore, Dunedin, New Zealand 9010" \ --base 1000 -r -X 0 \ -s -8760h -w 790 -l 0 --lazy # # Graph for temperature, Dalmore, Dunedin # -- YEAR (mark 2) # rrdtool graph /var/www/rrdtool/temperature-year2.png \ DEF:in1now=/var/www/rrdtool/temperature.rrd:internal:AVERAGE \ DEF:in2now=/var/www/rrdtool/temperature.rrd:inside:AVERAGE \ DEF:outnow=/var/www/rrdtool/temperature.rrd:outside:AVERAGE \ DEF:in1min=/var/www/rrdtool/temperature.rrd:internal:MIN \ DEF:in2min=/var/www/rrdtool/temperature.rrd:inside:MIN \ DEF:outmin=/var/www/rrdtool/temperature.rrd:outside:MIN \ DEF:in1avg=/var/www/rrdtool/temperature.rrd:internal:AVERAGE \ DEF:in2avg=/var/www/rrdtool/temperature.rrd:inside:AVERAGE \ DEF:outavg=/var/www/rrdtool/temperature.rrd:outside:AVERAGE \ DEF:in1max=/var/www/rrdtool/temperature.rrd:internal:MAX \ DEF:in2max=/var/www/rrdtool/temperature.rrd:inside:MAX \ DEF:outmax=/var/www/rrdtool/temperature.rrd:outside:MAX \ VDEF:MaxIn1=in1max,MAXIMUM \ VDEF:MinIn1=in1min,MINIMUM \ VDEF:AvgIn1=in1avg,AVERAGE \ VDEF:CurrentIn1=in1now,LAST \ VDEF:MaxIn2=in2max,MAXIMUM \ VDEF:MinIn2=in2min,MINIMUM \ VDEF:AvgIn2=in2avg,AVERAGE \ VDEF:CurrentIn2=in2now,LAST \ VDEF:MaxOut=outmax,MAXIMUM \ VDEF:MinOut=outmin,MINIMUM \ VDEF:AvgOut=outavg,AVERAGE \ VDEF:CurrentOut=outnow,LAST \ COMMENT:"\t\t\tMax\t\t\t\t Min\t\t\t\t\t Average\t\t\t\tCurrent\n" \ AREA:in2max#00FF00:"Inside" \ GPRINT:MaxIn2:"%8.2lf deg C" \ GPRINT:MinIn2:"\t\t%7.2lf deg C" \ GPRINT:AvgIn2:"\t\t\t%8.2lf deg C" \ GPRINT:CurrentIn2:"\t\t%8.2lf deg C\n" \ LINE1:outmax#FF0000:"Outside" \ GPRINT:MaxOut:"%7.2lf deg C" \ GPRINT:MinOut:"\t\t%7.2lf deg C" \ GPRINT:AvgOut:"\t\t\t%8.2lf deg C" \ GPRINT:CurrentOut:"\t\t%8.2lf deg C\n" \ --title "Temperature, Dalmore, Dunedin, New Zealand 9010" \ --base 1000 -r -X 0 \ -s -8760h -w 790 -l 0 --lazy I believe the graphs are correct now. My main giveaway before to the fact that something was wrong was that my yearly MIN was a higher number than my monthly MIN, and also my yearly MAX was lower than my monthly MAX. With the new changes, this is no longer the case :) Naturally, please let me know if you believe I have made any other mistakes. Thanks Alex, and the rest of you that make this a fantastic list.
