NAME ^

GD::Graph::splined - Smooth line graphs with GD::Graph

SYNOPSIS ^

        use strict;
        use GD::Graph::splined;

        my @data = (
            ["1st","2nd","3rd","4th","5th","6th","7th", "8th", "9th"],
            [    5,   12,   24,   33,   19,undef,    6,    15,    21],
            [    1,    2,    5,    6,    3,  1.5,    1,     3,     4]
        );

        my $graph = GD::Graph::splined->new;

        $graph->set(
                x_label => 'X Label',
                y_label => 'Y label',
                title => 'A Splined Graph',
        );
        $graph->set_legend( 'one', 'two' );
        $graph->plot(\@data);

        open(OUT, ">splined.png") or die $!;
        binmode OUT;
        print OUT $graph->gd->png;
        close OUT;

DESCRIPTION ^

A GD::Graph module that can be treated as an area graph, but renders splined (smoothed) line graphs.

See GD::Graph for more details of how to produce graphs with GD.
