Regression when using gnuplot and loops?

I am encountering problems when running gnuplot in
a loop (to update the graph based on changing data,
"poor man's animation").

When using the wxt terminal, I intermittently run
into a failed assertion:

Gdk:ERROR:/build/gtk+2.0-KsZKkB/gtk+2.0-2.24.30/gdk/gdkregion-generic.c:337:miSetExtents:
assertion failed: (pExtents->y1 < pExtents->y2)

When using the qt terminal, I can't stop the loop,
because the "bind" command does not seem to work.

These problems seem new to me. They may be due to
some form of library version skew (I updated my
Linux install in the meantime).

The essential commands are:

end=0
while( end==0 ) {
splot "file" i 1 matrix w p lc pal
pause 0.1
}

I have also encountered the following stacktrace

I am encountering problems when running gnuplot in
a loop (to update the graph based on changing data,
"poor man's animation").
When using the wxt terminal, I intermittently run
assertion failed: (pExtents->y1 < pExtents->y2)
When using the qt terminal, I can't stop the loop,
because the "bind" command does not seem to work.
These problems seem new to me. They may be due to
some form of library version skew (I updated my
Linux install in the meantime).

Is the below related for you ?
https://sourceforge.net/p/gnuplot/bugs/1592/

Or do you use "regression" related something like this?

BTW, just from curiosity, how do you get Compile options?

Yes, I seem to have a problem similar to the
bug report in the link.

I am on Linux Mint 18 (debian/Ubuntu based), and
I am using the gnuplot version that shipped with
the distro.

This leaves the behavior of the "bind" command when
using qt. I saw that the qt terminal does run in a
separate process - does this mean that I should not
expect "bind" to work, because there is no good way
to send a msg back to the gnuplot proc from the qt
terminal?

Gnuplot process and gnuplot_qt process communicates each other.
Bind command code is implemented source code for qt terminal
so it should work.

I execute a simple test on gnuplot-5.0.5 on windows and lubuntu 16.04 (built myself).

gnuplot> bind d 'plot x*x'
gnuplot> set term qt
gnuplot> bind d
d `plot x*x`
gnuplot> plot x

On qt plot windows, press d key => plot x*x
executed.

Bind command works for me on qt at least in the above simple example.

I made further test on qt and wxt terminal on gnuplot 5.0.5 windows and lubunutu 16.04.

bind d "end=1"
i=1; end=0; while (end==0) {plot i*x title "".i; i=i+1; pause 0.1}

press "d" on plot window of qt terminal can stop the loop for me.

But above loop is too simple so that it may not give a clue for this issue.

I think it depends rather critically on the length
of the pause and the complexity of the plot.

Apparently, qt is slower than wxt - timing that
worked for wxt did not work at all for qt.

Perhaps it depends on environments.
On my lubunutu 16.04, concerning speed for all.dem at "make check",
qt is faster than wxt.

(On windows, for all.dem execution, qt is rather faster than wxt. )

Back to the original issue,

Gdk:ERROR:/build/gtk+2.0-KsZKkB/gtk+2.0-2.24.30/gdk/gdkregion-generic.c:337:miSetExtents:
assertion failed: (pExtents->y1 < pExtents->y2)

is not gnuplot specific after google search.

As you wrote in the first post

They may be due to some form of library version skew
(I updated myLinux install in the meantime).

Perhaps this is an issue of some form of library version skew.
There seems to be difficulty in libraries of GTK+2, wxGTK and gnuplot.

If you have a chance to build gnuplot by yourself,
--with-wx-single-threaded
at configure sometimes changes the situation.
(However, it may reduce the speed.)

Thanks for the hint! I'll give it a shot.

(But it may be a while before I get around to it!)

The below is also similar to your case.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=834396

In the above, as workaround, build gnuplot with --with-wx-single-threaded option is described.
