Follow-up Comment #4, bug #45469 (project octave):
Dear Octave community,
Many thanks to all of you for your swift reply on bug report #45469 and your
good proposals.
Because of lack of time I am not able right now, to strip down my program to
its non-proprietariness and maintaining the reported bug.
The graphics tool used is indeed Qt, and I have not yet done experiments with
gnuplot or FLTK. However, I succeeded to circumvent the problem in the way
described below. The problem seems to be caused by the interaction of the
program with the external package io-2.2.8.tar.gz which I have to load in
order to create xlsx-files (Excel) with the xlswrite command.
The Octave 4.0.0 version comes with the io-2.2.7 package (in src
sub-directory) but I could not use xlswrite with this. So I downloaded the
newer package io-2.2.8.tar.gz from your website.
I entered (some days before, may not be important): pkg uninstall
io-2.2.7.tar.gz.
Whenever starting Octave, I have to feed in: pkg install io-2.2.8.tar.gz
with io-2.2.8.tar.gz in my working-directory. When I now enter: “pkg load
io”
and run the program, sooner or later the plot error reported in #45469 occurs.
So I did the following:
I omit issuing “pkg load io” prior to running the program and instead
have this line now in my program immediately before the first xlswrite
statement. After the last xlswrite a line: “pkg unload io” is executed.
Then the next circle with plot-statements starts and the same sequence for
xlswrite is repeated.
With this method the program execution is stable and no errors occur (up to
now).
By the way: A similar plot error within a for-loop was reported in #45298, but
i could not figure out, if or which io-package was used in that case.
There are some minor bugs with the xlswrite-statement itself, which I will
report in another message, so that xlswrite might get fixed in a future issue.
Again, many thanks to all of you for your help,
yge
