Re: help with rrdtool::oo and dinamic draw

it looks like the graph method, (though not shown) is converting the calling parameters into a hash. And that's what you start off expecting when suddenly you put @draw at the end of the call parameters, which has three elements (forcing total odd). You need to exchange @draw for something like some_key => \@draw I would imagine.

Hi! Thanks, a step further :-) and now .. `foreach my $row (@sensor_h) { push(@draw, { file => "../data/$row.rrd", legend => "Source 1", thic +kness => 2, color => '00FF00' }); }` [download] `$rrd->graph( #image => '-', image => "../images/" . $sensor . ".png", vertical_label => 'Sensors', width => $width, height => $height, start => time() - $period, draw => { file => "../data/sensor1.rrd", legend => "Source + 1", thickness => 2, color => '00FF00' }, draw => $draw[0], draw => $draw[1], ... and so on ... );` [download] yes, so works but i need to pass or join a hash with more draw occurrences thanks	[reply] [d/l] [select]

$rrd->graph(

  draw           => $draw[0],
