If I understand you correctly, you are looking for an on-screen device that displays the results, drops out of the event loop to allow the program to continue and does not close, so that later on you can resume the plotting. (As I do not know PGPLOT, I want to make sure I understand it.) plspause() will do that indeed, but the graphics buffer may get in the way.
Try using plflush() at the end of drawing the graph. I have not tried it, but I think that will help.

Subject: [Plplot-general] Does plplot have an equivalent of PGPLOT's /xserve device?
Hello, I am new to plplot, but I am trying to check it for a number of applications I have in mind within C++ and Python codes as a replacement for PGPLOT which I have used for years. I am starting with the Python binding to explore plplot's features. The interactive device I use most of all with PGPLOT is "/xserve" which allows you to generate a plot that persists after a program / script exits and returns control to the terminal. I use this feature all the time. Within long running programs, it allows me to generate plots which I can look at while the program continues doing something else. With plplot's xwin or tk, I can get a plot that persists, but it seems to block until I have actively quitted it. I experimented with calling plspause(False) just before plend but then the plot just flashes briefly with tk and does not appear at all with xwin.
I feel I am missing something obvious, but haven't found it yet. Thanks in advance for any help,
