Heya, There isn't any performance difference between QThreads and python Threads; that's mostly a difference of how you want to integrate with Qt (QThreads fit into the rest of the Qt lifecycle better). Otherwise, the question that I ask to determine thread v. multiprocess is: will my worker mostly be sitting around waiting? If that's the case (e.g. waiting on i/o), then using a thread is great. Otherwise, if the worker needs to do a bunch of heavy work before the data is ready to display (e.g. it's the output of a difficult analysis), put that work on a different core.
Only matplotlib is as good at plotting as matplotlib; it's the best python plotting library. If that's your minimum bar, I agree that you'll be writing everything yourself from scratch. PyQtGraph is built for performance, though, so you're going to need the best of both libraries if that's your use-case. Good luck, - Martin -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
