Momentary traffic column

Hi all,

I try to visualize the momentary throughput of a TCP connection in a custom column, just to get an idea of how latency effects throughput. If I understood correctly, this should be achieved by tcp.len / tcp.analysis.ack_rtt or maybe by tcp.len / tcp.time_delta. Both expressions are not accepted by Wireshark. I assume because the denominator may be zero? Generally, division works, e.g. tcp.len / ip.len works.

Do you have any idea how I can make this work?

Regards, Lukas
