Well, you are correct. Finally, my latest post to the MPL list caught
the eye of John Hunter. I think he wrote MPL. The way out is interactive
use. One problem I've had with Python packages they "seem" to based
on some other product, which one is supposed to know. I sight Tkinter
and now MPL. I last used MatLab five years ago, and wrote some simple
programs in it, so at least I have a very modest idea of how it works. I
may have to use it to grsp the interactive mode.
This problem has been a difficult one get a grip on. I've had socket
error problems, difficulty getting Matlab back up on my machine, a
possible install problem, and a host of ambiguities about this use. The
end is near.

Hi, I'm not so sure that's true. I have a large 900 line program where
some original plot code just continues beyond plot() and show(), after
the user closes the plot window. New code that I put in gets knotted
up, as far as I can tell. In both cases, I've put print statements
after show(), but nothing appears in the shell or, if run by clicking
the program file, in the DOS-like window that appears.
Further, I posted this elsewhere, and someone claims to have tried a
few simple examples with show() at the ended,and they did not get tied
up in knots when the user closed the window. I'm going to assume he
used IDLE, or a straight execute of the file.

The basic problem is the show(). One person checked out the examples I
provided and found show() to operate fine. On my XP machine the program
I'm modifying has plot code someone put in a year or two ago, and it

show().
The behavior that you describe, is the normal behavior of Matplotlib:
When you
call show(), the program gets stuck.
Therefore the call to show is always the last statement in the example
programs. Show returns when the last plot window is closed, and in
principle
the program could then continue.
If you want to look at plots while the program is running, you must use
Ipython. This is a modified Python interpreter, that contains special
code to
change the way how Matplotlib works.
