Moins,
I have some data to create a graph. I create one graph with a size, which it's the standard size. So I don't set width and height. In this graph the VDEF for MINIMUM is correct calculated. Then I create a second graph, bigger than the other with the width of 1024pixel and heigth of 768 pixel. All other Definitions are the same like the first. But here the VDEF for MINIMUM don't calculated correct. The value is to high. So here is a link to the little Graph: http://www.mordur.de/0014.f83d.cd16_12.png And the big: http://www.mordur.de/0014.f83d.cd16_12_big.png You can see that the MINIMUM in the big pic is incorrect. Here are the commands to create: Normal Pic: rrdtool graph /srv/www/htdocs/modreport/pics/0014.f83d.cd16_12.png --start 1245813840 --end 1245921840 --title='1.3.6.1.2.1.10.127.1.1.4.1.2.3 von 0014.f83d.cd16' -X 1 --vertical-label='_' --color CANVAS#EEEEEE --color GRID#FF5000 --color AXIS#0000A0 --color ARROW#0000A0 DEF:myoid=/srv/www/htdocs/modreport/reports/0014.f83d.cd16_12.rrd:OID_12 :AVERAGE CDEF:realoid=myoid,1,\* VDEF:min=realoid,MINIMUM GPRINT:min:"Minimum %.2lf " VDEF:max=realoid,MAXIMUM GPRINT:max:"Maximum %.2lf " LINE1:realoid#0000A0 Big Pic: rrdtool graph /srv/www/htdocs/modreport/pics/0014.f83d.cd16_12_big.png --start 1245813840 --end 1245921840 --title='1.3.6.1.2.1.10.127.1.1.4.1.2.3 von 0014.f83d.cd16' -X 1 --vertical-label='_' --color CANVAS#EEEEEE --color GRID#FF5000 --color AXIS#0000A0 --color ARROW#0000A0 --width=1024 --height=768 DEF:myoid=/srv/www/htdocs/modreport/reports/0014.f83d.cd16_12.rrd:OID_12 :AVERAGE CDEF:realoid=myoid,1,\* VDEF:min=realoid,MINIMUM GPRINT:min:"Minimum %.2lf " VDEF:max=realoid,MAXIMUM GPRINT:max:"Maximum %.2lf " LINE1:realoid#0000A0 The MAXIMUM is correct calculated in both. I've check this whith a rrdtool fetch at the real values. regards Sven Rothe ALBAKOM GmbH Streuwiesenweg 44 18119 Rostock-Diedrichshagen Tel.: 0381-77896-30 Fax.: 0381-77896-33 e-mail: [email protected]
