Hello to everyone -
I intend to use the GD::Graph::area module for generating simple area graphs. Although i have searched the cpan and other resources, i still haven't figured out how to set the axis origin to zero so that the x-axis and the y-axis will start from zero both (from the same point).
here is my code:
use GD::Graph::area;
use GD::Graph::colour qw(hex2rgb);
print "Content-type: image/png\n\n";
my @data = (
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
);
my @names = qw/sample21/;
for my $graph (GD::Graph::area->new)
{
my $name = shift @names;
#print STDERR "Processing $name\n";
$graph->set(
title => 'An Area Graph',
dclrs => ['green'],
#accentclr=>'red',
y_max_value => 10,
x_max_value => 10,
x_min_value=>0,
y_min_value=>0,
y_tick_number => 5,
x_tick_number => 5,
overwrite=>1,
#ticks_length=>,
#y_label_skip => 2,
#x_label_skip => 0,
x_tick_offset=>1,
#y_plot_values=>1,
#x_plot_values=>1,
#correct_width=>1,
#accent_treshold => 20,
transparent => 1
);
#$graph->set_legend( 'one', 'two' );
my $im = $graph->plot(\@data);
print $im->png;
}
Does anyone have any idea how to do this ?
