Using the following config values you can now disabled the Top X boxes:
$config['top_ports'] = 1; // This enables the top X ports box
$config['top_devices'] = 1; // This enables the top X devices box
Top X boxes can now be switched off
We need a better method than this in the long term (it won't scale if we have 10 different top 10 graphs), but it'll do for now.
