I was hoping you could help me out. My problem occurs using the rtr-graph script, a perl script program developed my John Shearer. He tried to help, but to no avail.

I get this error when trying to execute the rtr-graph:

# /usr/local/bin/rtr-graph --cfg traffic.cfg

Can't call method "png" on an undefined value at /usr/local/bin/rtr-gr
+aph line 123.

# more rtr-graph

$my_graph->set_legend_font  ("gdMediumBoldFont");
$my_graph->set_legend( 'Traffic Out', 'Traffic In' );
my $gd = $my_graph->plot(\@data)->png;                        
   open (IMG, ">$tmp_dir/graph.$name.$int.png") or die;
    binmode IMG;
     print IMG $gd;
       close IMG;

John, the developer of the script, told me to verify if I had the files referenced in the script and whether they had data.

Here are my files:

[root@atilla tmp]# ls -ltr
total 52

-rwxrwxrwx    1 root     root           30 Oct 20 13:33 traf.traffic.2
+0031020.6
-rwxrwxrwx    1 root     root           21 Oct 20 13:33 traf.traffic.2
+0031020.5
-rwxrwxrwx    1 root     root           15 Oct 20 13:33 traf.traffic.2
+0031020.4
-rwxrwxrwx    1 root     root           15 Oct 20 13:33 traf.traffic.2

and the data within the files is:

more traf.traffic.20031023.2

1066947054 0 0
1066948418 0 0

If you could point me in the right direction at all, I would really appreciate it.
