TOTALSUM, TOTALAVG are really ugly suggestions for names. =) Or alternately make TOTAL a raw sum and supply a COUNT and STEPS so we can calculate it manually? -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-developers WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
