Do --lower-limit or --upper-limit accept VDEF variables as values ? All the examples I have seen use actual numeric values within the upper/lower commands to fix the Y-axis but I would like to have it more dynamic based on the values within the graph itself.
I have a set of data (hard disk temperatures) which I have manipulated with CDEF and VDEF to arrive at simple numeric values related to the maximum and minimum temperature seen on the graph. These are stored in VDEF variables. I can plot LINEs using the above VDEF values for position yet when I use the same VDEF variable names in the lower/upper limit commands they are either ignored or force the wrong scale. I realise that auto-scaling is doing this for me but I would like more control. I can substitute variables into the lower/upper commands from outside the rrdtool graph command with $variable etc but then cannot see a way of creating the same values I found via CDEF and VDEF via the script (using rrdtool fetch etc). So my question is, should this work and I am doing it wrong or does upper/lower-limit not support VDEF substitution for values ? I am running RRDTOOL on a synology NAS as a pre-compiled IPKG package, listed as version 1.2.30-1 Many thanks. -- View this message in context: http://rrd-mailinglists.937164.n2.nabble.com/Upper-Lower-limit-and-VDEF-tp7581778.html Sent from the RRDtool Users Mailinglist mailing list archive at Nabble.com. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
