Hello,
As everyone suggested here,using GD::Graph is good enough for creating that
chart.
Here are the codes I once wrote for creating the bars,wish it's a reference for
you.
package graph;
use strict;
use GD::Graph::bars;
use CGI;
sub newImage
{
my ($class,$data,$length,$width,$max_y_value) = @_;
my $graph = GD::Graph::bars->new($length, $width);
$graph->set(
x_label => 'CLOCK',
y_label => 'PV',
title => ' ',
bar_spacing => 12,
show_values => 1,
# values_vertical => 1,
y_max_value => $max_y_value,
box_axis => 0,
) or die $graph->error;
my $gd = $graph->plot($data) or die $graph->error;
print CGI->header("image/png");
binmode STDOUT;
print $gd->png;
}
1;
And calling it with this like way,
use graph;
my @out = ([xx,xx,xx,xx],[xx,xx,xx,xx],...); # datas to fill
graph->newImage([EMAIL PROTECTED],'755','205',$max_y_value);
