Hello - I have a pretty PNG:

http://dodgeit.com/temp/file.png

created with this code: 

my $chart = GD::Graph::lines->new(1000,480);
$chart->set(x_label => "time",      # no axes for pie chart
            x_labels_vertical => 1,
            x_label_skip => 50,
            y_label => "price",
            title   => "misc stock",
            long_ticks => 0,  # make a grid of all the ticks
           );
my $plot = $chart->plot($dataref) or die $chart->error;

I'd like to draw a horizontal reference line right at the number 11.

Any ideas? I looked through the /samples dir that came with the GD::Graph dist and didn't find anything promising and have also googled around quite a bit.

TIA -> Phil
