To what extent could code be shared between them - and exported to other taps that draw graphs (present or future)?

There is a fair bit of functionality that they have in common, there are relatively few places that are really specific to my different protocol (LTE RLC).  I did end up taking out the control panel window and magnifying tool for my version, so there are now several places where I had to avoid trying to look at the state of widgets that for me don't exist, which may make factoring out common code a little bit trickier.  As far as I can tell mine is the only other time-sequence graph based upon the tcp_graph code (io_stat.c looks like it was written quite independently).

I am undecided about this... I don't know how many protocols are out there that lend themselves to this kind of graphing.  I had wanted to do mine for a long time, but was put off by how complicated I thought it was going to be.  If there was a nice, well-documented framework with obvious places to put my protocol-specific hooks, I might have created my tap a long time ago.

I will have a go at pulling common code out into a separate file and see if it looks like it'll be worth it.
