hmm not really if you quit the sketch you close the sketch window. but you can stop running the sketch which doesnt close it though. Why do you want to do that, maybe we can give some other solutions to your problem.

I am creating a Logic Analyzer to display line traces on/off states. I don't want it to run
when no new data is coming in and I don't want the chart to disappear when it stops running.
When it is running with noLoop() it still puts a load on the CPU.  In the past I have used GNUPlot
which does the trick but is really CPU heavy and wouldn't work for this task.

Any ideas?

Thanks for your time.

What system do you use? A Mac? I just tested a small sketch ending up with noLoop() (and no event listener...), and it uses near zero CPU in this state. On Windows 7.

If you stop the sketch, the windows it displayed are closed as well. You can save an image and use an image viewer to display it, perhaps. Or set it as desktop background...

" How do I save an image?"
Search save in the reference... (yes, Processing is often that simple... )

" can I then create a new scaled up view with that rectangle and still keep the old one?"
Yes, you can.
