In Ethereal Ver 0.10.3 if you display the IO Graph and use the Advanced option on the Y axis, the manual doesn't seem to explain what the SUM & COUNT options are trying to do. As an example if you set the filter on the graph to:-

(ip.src == 128.101.80.131) && (tcp.dstport == 33543)

and the COUNT to:-

tcp.dstport

I assume the graph just plots the number of TCP packets whose destination port is set to 33543 from IP address 128.101.80.131 against time?

If you now change the same graph from COUNT to SUM with the filter & fields the same as before, what is this plotting?
