Hi Tom:

I have been following your conversation with Arjen with interest, and
I think what you describe above is exactly what we provide.  But I
might be interpreting what you said above incorrectly so let me make
clear what we provide with an exact example.

In the build tree, if I build the xwin device and one of the simplest
examples with the following commands:

# Create xwin device and all its dependencies
make xwin
# Create a particular C example and all its dependencies
make x00c

then when I run

examples/c/x00c -dev xwin

the plot persists on the screen and the C example does not quit.  In
fact, I can resize that plot so it does remain active until I exit
from it (by hitting the enter key or clicking on the button to destroy
the X window).  So it appears to me this default behaviour of the xwin
device is exactly what you described above.

You expressed and interest in Python so here is the equivalent there

# Create xwin device and all its dependencies
make xwin
# Create Python binding for PLplot
make _plplotcmodule_fixed
# Populate build tree with python examples
make python_examples

Then run

examples/python/x00 -dev xwin

and that plot has the same desired characteristics as the C version above.

Will you try either the C version or Python version of the concrete example
above, and let us know what (if anything) the difficulty might be?
