[Pkg-octave-devel] Bug#805295: octave: Plot to file without X display does not work

[Djalil Chafai]

Package: octave
Version: 4.0.0-5+b1
Severity: normal

Dear Maintainer,

consider the following code stored in file plotest.m

# begin
graphics_toolkit('gnuplot')
set(0, 'defaultfigurevisible', 'off');
plot(sin(1:100));
print("plotest.jpg", "-djpg")
# end

bash> export DISPLAY=
bash> octave plotest.m

The image file plotest.jpg contains a fully black figure. It should not.

Best wishes.
