How about running through an RRD Graph once, but rather than drawing anything, use PRINT (NOT GPRINT) to get the minimum value of ausen and then you have a value (Perl variable) you can use as a constant in a second RRD Graph run. So use VDEF to get the min value, then do some maths (further CDEFs) to draw the pumpe value between this min value and 1 > Sorry English is not my native language and school is long ago No need to apologise, your English is a lot better than my German from school (also a lot of years ago) ! ___ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users

> All looks fine as lpng as the outdoor temperatrure is above 0 degree. > Otherwise the pump graph ends at the O line, it looks ugly! In other words: you only have a problem with >CDEF:OnOff=PUMPE,FLOOR,80,*", >"AREA:OnOff#F0EFEF:Umwaelzpumpe ", Not sure if it will work, but try this: CDEF:OnOff1=PUMPE,0.5,LT,UNKN,INF CDEF:OnOff2=PUMPE,0.5,LT,UNKN,NEGINF AREA:OnOff1#F0EFEF:Umwaelzpumpe AREA:OnOff2#F0EFEF If you need to fix some error in my RPN, then here is what it is supposed to do: if PUMPE < 0.5 then return UNKN else return INF into OnOff1 if PUMPE < 0.5 then return UNKN else return -INF into OnOff2 Draw both OnOff as an area, just print one label. INF will not modify the Y-axis, it will just fill the entire vertical space available. If there are no negative rates, then I do not expect to see anything from that second CDEF. But if there are negative rates, this CDEF will show up, and it will look as if it is one big area from -inf to +inf. I assumed you enter 0 or 1 for pumpe, and I chose an arbitrary 0.5 as the cutoff point. You can and should change this value if your situation is different. Do not test for being equal to 1 or not. That won't work if there is any normalization or consolidation happening. HTH Alex ___ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
[rrd-users] RRDs::graph and DEF... MIN
Hi, I am monitoring my heating by a raspberry-pi using rrd data base: - TMP_V = flow temperature - TMP_R = return temperature - WOHNZ = indoor temperature - AUSEN = outdoor temperature - PUMPE = circulating pump (running or not) The graph wil be drawn by perl script using RRDs::graph (librrds-perl 1.4.7-2+rpi1): RRDs::graph($tmpfile, @opts, "DEF:TMP_V=/home/pi/heizung.rrd:hzg_v:AVERAGE", "DEF:TMP_R=/home/pi/heizung.rrd:hzg_r:AVERAGE", "DEF:WOHNZ=/home/pi/heizung.rrd:wohnz:AVERAGE", "DEF:AUSEN=/home/pi/heizung.rrd:ausen:AVERAGE", "DEF:PUMPE=/home/pi/heizung.rrd:pumpe:AVERAGE", "CDEF:OnOff=PUMPE,FLOOR,80,*", "AREA:OnOff#F0EFEF:Umwaelzpumpe ", "LINE1:OnOff#424242:", "LINE2:0#00:", "GPRINT:PUMPE:LAST:akt.\\:%5.1lf", "GPRINT:PUMPE:MIN:min\\:%5.1lf", "GPRINT:PUMPE:MAX:max\\:%5.1lf", "GPRINT:PUMPE:AVERAGE:mittel\\:%5.1lf\\n", "LINE2:TMP_V#FF:Vorlauftemp.
