RRDtool uses fixed-width intervals by design. A month has no specific length: Januari: 744 hours Februari: 672 hours, or 696 in about one out of four years March: 743 hours (assuming summer time kicks in) April: 720 hours May: 744 hours ... October: 745 hours (assuming end of summer time occurs here) November: 720 hours December: 744 hours > Is it possible (and if yes, how)?

You need a drawing program, not rrdtool. -- Alex van den Bogaerdt http://www.vandenbogaerdt.nl/rrdtool/ -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
