the error message is displayed sometimes, I have executed the script on two
MSWIN10-computers under Octave v6.2.0 and on both I have seen this error
message, but after restart of Octave the error-message disappeared on one
The script seems to be correct, under Ubuntu 20.04/Octave v5.2.0 I can plot
and open the resulting HTML-file in a browser, but the same HTML (created on
the Linux-machine) cannot be displayed under MSWIN10.
It seems as if my text added as "raw text" cannot bee seen by everyone,
therefore, I add it here again:
graphics_toolkit('gnuplot'); figure(1); plot([1:5]);
print(1, '-dcanvas', 'd:\tmp\test_MSWIN10_Octave_6.2.0.html');
Attached the two different HTML-plot-files.
