In any report, when I cilck the third display mode (“radar”) I’m getting a blank “graph” and:

I’m running 3.2.0.beta5-dev [d0486a72ac](https://github.com/discourse/discourse/commits/d0486a72ac5eb71cd5511999e3a5614fe701fb3f), I know I’m a few commits late but I see no commit mentionning “radar”. I’ll try to update but at night in case of downtime during upgrade.
