OVERLIBGRAPH function does not work

[qwertz]

Hello,

I configured weathermap successfully.
Thanks for this beautiful script.

I tried to activate the mouse over capability with OVERLIBGRAPH.

LINK blabla
NODES bla bla
OVERLIBGRAPH http://link

The problem is that it doesn't work, on mouse over, i have nothing.
Can you help me?
What could i do to help troubleshooting the problem?

Thanks

PS:
Other little problemM
After a php polling, i see in the in cacti log:
Notice: Use of undifined constant WEATHERMAP - assumed 'WEATHERMAP' in /var/www/html/cacti/plugins/weathermap/setup.php on line 272
I did not change anything and despite this message everything (except mouse over capability) work perfectly.
