Help with LibreNMS dashboard

Hello guys, I wanna know how can I add on my dashboard a graph with interfaces speed of my principal router.

see here Help With the dashboard
you add the Graph Widget.
then Graph: Bits
Range: set to whatever you want.
Port: is the interface of the device you want to graph.

Thanks Kevin, but the graph is showing many interfaces of my device,do you have a method to filter it?

in the Port section, you should be able to select what interface you would like. can post a screen shot of what are you talking about?

Thanks again Kevin, I was using bits on device section, now I’m using on port section and my graphs are correctly now.
Thank you so much for help !
Best regards!
