Traffic Graphs on Dashboard not loading with certain types of interfaces
0%
Description
Traffic Graph is not loading at all when GRE, OpenVPN or IPSec graphs are enabled because it doesn't receive data for those.
The JS Console logs this
Uncaught TypeError: Cannot read property 'update' of undefined
at Array.<anonymous> (traffic-graphs.js?v=1542803994:332)
at Function.each (jquery-1.12.0.min.js?v=1542803994:2)

It would be fine if only that one graph wouldn't load, but all graphs refuse to load then. An additional check here to make sure that only one graph fails in case something similar happens again would be a great addition aswell.

I've tried those interfaces here and graphs work fine. Might be something specific to your environment. If you still have this issue, please post on the Netgate Forum .

This seems to be a race condition somehow, it doesn't always happen and I think it was loading for me before after disabling a few because they were less graphs and they took less time to load, maybe the JS is running before the browser rendered the Graphs properly. My fix to this is line 332 of traffic-graphs.js to
if (charts[key]) { charts[key].update(); }
It would be great if someone could update the "official" traffic graphs with this little enhancement.
