Hi RRD users, In one of my RRD graphs I would like to draw lines of maximum and minimum valid value. I have a gauge variable that varies greatly, and I want to add a maximum line at +40, and a minimum line at -40. This way, anyone who looks at the graph can see if the value plotted from the archive is valid or not. I know I can do this with RRD. From the documentation (http://oss.oetiker.ch/rrdtool/doc/ rrdgraph_rpn.en.html) I see that I can define a VDEF expression. Could someone please give me an example of how I would define this expression to give the lines that I need? This does not seem to work:
DEF:ds1=/path/to/myrrd.rrd:mass:AVERAGE LINE1:ds1#000000:"mass position" VDEF:limits=ds1,-40,40,LIMIT LINE1:limits#333333:"Limits" Thanks in advance, - Rob -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
