I think, this has more to do with the driver you are using, i.e. the plplot library processes all plot commands immediately, but the driver only updates the screen now and then. plflush() forces the driver to update the screen. We had this discussion already (23. August 2009), but I think we didn't come to a conclusion, or anything was changed accordingly. Which driver do you use?
