A switch does not "use" any traffic ... well if it does, something is badly wrong.
Much more it would be interesting to see graphs covering all switch ports, ingress and egress. Should not be difficult to generate a much more meaningful graph, the pure numbers are available on the port view.
Some other graphs make use of KBPS and MBPS ... these units do not exist. kB/s MB/s [Bytes] or kb/s Mb/s [Bits] are standard.
As a side comment, we see various non-translated content, AM/PM times, ... once more, the world (with all due respect for President Trump) does no AM/PM. 8-)
