Not sure if this fits what you are trying to do, but have you tried
Statistics -> IO Graphs
Then set Units to Advanced. Select "AVG(*)" as the Calc method. Enter
tcp.analysis.ack_rtt
You can apply a filter in the appropriate location as well.
Note that you will need "Analyze TCP sequence numbers" activated in TCP
protocol options in Wireshark preferences for this to work.
