I'm not exactly sure what you are asking for, so here we go:

If you are asking for an IO graph for one stream:

  • open the IO graph: Statistics -> IO graph
  • enter the filter for your stream: == 1
  • select the unit (packets/tick or Bits/tick)
  • draw the graph

If you are asking for an IO graph for all tcp streams:

  • do the same as above, with a different filter: tcp

If neither of the above is what you want/need, please add more details.

Hi Kurt,when adding filter with eq 1 i can just see the flat line or rather say it doesnt show the graph.

are you sure that

  • there is a stream nr. 1
  • there are enough packets in the stream to draw anything
  • you pressed the "Graph 1" button

yes infact there are too many packets but only flat horizontal line is showing.

can you please add a screenshot of the IO graph window to your question? Did you try to change the Scale: settings?

BTW: What is your Wireshark version and OS?

Select a packet of the desired tcp session in the desired direction and go to

Statistics -> TCP StreamGraph -> Time Sequence Graph (Stevens) and you'll get the increments of the sequencenumbers over the time. alt text
