[Qt-interest] real time strip chart

[Jason H]

Thanks. I remember that trick back in my old BASIC days. PSET was actually very 
close compared to LINE in performance, depending on how many points were being 
updated -- large I/O delays o ntht old hardware -- But now with double buffering 
and way faster buses of today, he should be able to do quite well.

  That’s a clever idea and our original questioner should definitely benchmark
  that; depending on how many traces are being drawn simultaneously, I
  wouldn’t be surprised if that’s the winner!
