Afternoon-- I'm having a few problems recording and graphing snow fall. My last recorded time seems to be 12 hrs prior than it shuld be. Any tips would be appreciated. Also, How can I display the total snowfall for the season on a graph? I have a rrd db setup with the following: /usr/bin/rrdtool create ../snow.rrd --step 43200 \ DS:snow12:GAUGE:86400:0:48 \ DS:moisture:GAUGE:86400:0:5 \ DS:snowstake:GAUGE:86400:0:120 \ RRA:AVERAGE:0.5:1:288 \ RRA:AVERAGE:0.5:3:672 \ RRA:AVERAGE:0.5:6:1344 \ RRA:AVERAGE:0.5:6:17532 \ RRA:MIN:0.5:1:288 \ RRA:MIN:0.5:3:672 \ RRA:MIN:0.5:6:1344 \ RRA:MIN:0.5:6:17532 \ RRA:MAX:0.5:1:288 \ RRA:MAX:0.5:3:672 \ RRA:MAX:0.5:6:1344 \ RRA:MAX:0.5:6:17532 \
I update the db every 12 hrs from an HTML form. I'm using the following to graph my snowfall: /usr/bin/rrdtool graph /var/www/html/wxgraph/snow.png -s -86400 --units-exponent 0 -h 150 -w 300 -t " Inches of Snow" DEF:snow=/var/www/html/wxgraph/snow.rrd:snow12:MAX LINE2:snow#00FF00:"Snow" DEF:moisture=/var/www/html/wxgraph/snow.rrd:moisture:MAX LINE2:moisture#FF0000:"Moisture" 2>&1>/dev/null # # /usr/bin/rrdtool graph /var/www/html/wxgraph/snow2.png -s -86400 --units-exponent 0 -h 150 -w 500 -t " Inches of Snow" DEF:snow=/var/www/html/wxgraph/snow.rrd:snow12:MAX LINE2:snow#00FF00:"Snow" DEF:moisture=/var/www/html/wxgraph/snow.rrd:moisture:MAX LINE2:moisture#FF0000:"Moisture Content" 2>&1>/dev/null # # /usr/bin/rrdtool graph /var/www/html/wxgraph/wsnow.png -s -604800 --units-exponent 0 -h 150 -w 500 -t " Inches of Snow" DEF:snow=/var/www/html/wxgraph/snow.rrd:snow12:MAX LINE2:snow#00FF00:"Snow" DEF:moisture=/var/www/html/wxgraph/snow.rrd:moisture:MAX LINE2:moisture#FF0000:"Moisture Content" 2>&1>/dev/null # # /usr/bin/rrdtool graph /var/www/html/wxgraph/msnow.png -s -2678400 --units-exponent 0 -h 150 -w 500 -t " Inches of Snow" DEF:snow=/var/www/html/wxgraph/snow.rrd:snow12:MAX LINE2:snow#00FF00:"Snow" DEF:moisture=/var/www/html/wxgraph/snow.rrd:moisture:MAX LINE2:moisture#FF0000:"Moisture Content" 2>&1>/dev/null # # /usr/bin/rrdtool graph /var/www/html/wxgraph/ysnow.png -s -31536000 --units-exponent 0 -h 150 -w 500 -t " Inches of Snow" DEF:snow=/var/www/html/wxgraph/snow.rrd:snow12:AVERAGE LINE2:snow#00FF00:"Snow" DEF:moisture=/var/www/html/wxgraph/snow.rrd:moisture:MAX LINE2:moisture#FF0000:"Moisture Content" 2>&1>/dev/null /usr/bin/rrdtool graph /var/www/html/wxgraph/snowstake.png -s -2678400 --units-exponent 0 -h 150 -w 300 -t "" DEF:snowstake=/var/www/html/wxgraph/snow.rrd:snowstake:MAX LINE2:snowstake#00FF00:"Snow at the Stake " Thanks Kevin Plew Dad/webmaster Plewnet.com -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
