[Swift-devel] Plotting

[Ioan Raicu]

I also had scripts, and sometimes even Java programs that would take 
some large log(s) and summarize it, to make it easier to plot. 
Sometimes, plotting things was really a multi-stage process, but the 
plots many times came out looking pretty good in a relatively automated 
fashion. But it took lots of tinkering with scripts, programs, and the 
plotting software to make it happen, and much of it was specific to the 
logs I was looking at (in my case, they were Falkon logs).
