NAME

Chart::Clicker::Drawing::ColorAllocator

DESCRIPTION

Allocates colors for use in the chart. The position in the color allocator corresponds to the series that will be colored.

SYNOPSIS

    use Graphics::Color::RGB;
    use Chart::Clicker::Drawing::ColorAllocator;

    my $ca = Chart::Clicker::Drawing::ColorAllocator->new({
        colors => (
            Graphics::Color::RGB->new(
                red => 1.0, green => 0, blue => 0, alpha => 1.0
            ),
            ...
        )
    });

    my $red = $ca->get(0);
