cristian: yes, but my point was that for sctp this is done in a much more
intuitive fashion, which imo is more user friendly.

crisitian: yes, something like that. from what I understand from
martin this should be available in newer versions.

You don't get to flip the direction inside the graph window, but you can now also launch the graph in either direction from the conversation table window (see screenshot).  You could find the TCP connection that you are interested in, then click both graph buttons to launch both graphs.

Martin
