[rrd-users] Weekly graph not correct

[Wesley Schwengle]

Hello all,

I'm having some problems with graphing. When I want to display the last 7 days, however my graphs only show the last 4 days of data..

Below you will find the create and the graph statements which I use (http://search.cpan.org/~mschilli/RRDTool-OO-0.22/lib/RRDTool/OO.pm). I think it has to do with the rows statement in the create. Could one point me into the correct direction as I am fairly new to RRD tool.

$rrd->create(
     step        => 300,
     start       => time() - 24 * 60 * 60,
     data_source => {
         name      => 'impacted',
         type      => "GAUGE",
         heartbeat => 600,
     },
     archive => { cpoints => 1, rows => 1200, cfunc => 'LAST' }
);

$rrd->graph(
     image          => $img,
     vertical_label => 'Impacted users',
     start          => time() - ( 7 * 24 * 60 * 60),
     draw           => {
         type      => 'line',
         color     => '0000FF',
         thickness => 2,
         cfunc     => 'LAST',
     }
);

Cheers,
Wesley
