tcptrace may be one tool but may lack granularity you seek.
Take a look at http://wiki.ethereal.com/TcpPduTime
Basically, you can graph a number of things.
Notice that in the lower right corner of the IO Graph, you need to choose "Advanced"
In the first FILTER box, you may put something like "ip.src==10.1.1.1"
in the CALC field, you might choose a function of AVERAGE and type in "tcp.windows_size" in the blank field.
In the STYLE field, choose LINE.
This will chart the TCP window size but you get the idea of how this can be used.
