Hi @liquidxtc13,
I guess this is a behavior related to how the value is reported via SNMP. If you check the raw data (agent output directly or in the service view row Service performance data) I assume your firewall is returning the values in bytes and therefor you have the exponential axis in your graphs.
At the switch it my be kB or MB returned by SNMP which causes the graph to show other ranges the fit the values.
