in reply to Graph with VMstat output

My advice is to break down the problem into small junks which you can understand. First, see if you can create a GD graph manually with your data, then if successful, see if your object output is suitable for input to GD::graph.

GD graph has some nested arrays it uses for input, for example, see how the data is arranged in the following example. Make sure your input is like that.

#!/usr/bin/perl -w use strict; use GD::Graph::bars; my @data = ( [qw(a b c d e f g)], [1,2,3,4,5,6,7] ); my $graph = GD::Graph::bars->new(200, 200); $graph->set( transparent => '0', bgclr => 'lgray', boxclr => 'white', fgclr => 'white', cycle_clrs => '1', x_label => 'X Label', y_label => 'Y label', ); my $gd = $graph->plot(\@data); binmode STDOUT; #print "Content-type: image/png\n\n"; print $gd->png();

I'm not really a human, but I play one on earth.
