Hello, In my case http://host/cgi-bin/bindgraph.cgi showed embty graphs, without bars.
It seems to ge an user/permissions problem. /etc/init.d/bindgraph start didn' start the daemon. Why? Because it tries to start it under daemon:adm, but daemon is not member of adm by default in my system (wheezy). "nice -20 /usr/sbin/bindgraph.pl --daemon --logfile /var/log/bing9-query.log" works launched by root, but it doesn't work launched by daemon (error: bindgraph: can't write to /var/lib/bindgraph), because this directory is owned by root:adm 775. Making daemon member of adm in /etc/group manually shows the bars in the graphs. --
