[Plplot-devel] Am I using eop() or abusing it?

[Greg J. <gv...@gm...>]

GDL has had a problem in its use of the wingcc driver in that,
plotting additions to a basic PLOT call do not stick to the plot
 when it is moved or resized.  I've found that when I stick another
eop() call after each of these plot calls, the problem is "solved"
for this driver https://sourceforge.net/p/gnudatalanguage/bugs/689/#b1d7
because each eop() in wingcc induces another copy of the screen to the
 bitmap used for refresh.

  Jim's new wingdi driver doesn't have this issue although I can't see why
not.

According to the plplot-5.10 doc, eop() would close a plot file begun when
bop()
is called.  Currently rdbuf_eop() is a no-op although there is an EOP code
put
into the plot buffer.

My happy answer would be that a second eop() without bop() indicates a
re-open, "append" to the ongoing plot buffer (or file).  Is that consistent
with current usage?

Thanks,
Greg
