NAN in Docker graphs

Hi !
I’ve configured the Docker integration yesterday. After some struggling, I’ve successfully managed to add the ./docker-stats.py script to the sudoers file.

Now, the graphs show well for a container added this morning, but all other containers show up with NaN in the graph. Also, an output of the script shows that all data are correct.

Any idea ?
