[rrd-users] line1 with dashes in a perl cgi script

[Audio Phile]

I'm using version 1.32 of rrdtool via a perl cgi script.  I can do everyting EXCEPT generate graphs containing dashed lines.  It is due to my poorly formed syntax I believe in the cgi perl script.  I placed a # in front of the troublesome line.  Can someone show me the right syntax?

Thanks!

sub graph_temperature_history($$$)
{
        my $range = shift;
        my $file = shift;
        my $title = shift;
        my $step = $range*$points_per_sample/$xpoints;

        my ($graphret,$xs,$ys) = RRDs::graph($file,
                '--imgformat', 'PNG',
                '--width', $xpoints,
                '--height', $ypoints,
                '--start', "-$range",
                "--title= Current and Historical Temps in $city",
