Comment 2 for bug 1843629

A workaround is to tell octave to use gnuplot:

graphics_toolkit("gnuplot");

At least this worked now:

x = 0:0.01:2*pi;
y=sin(x);
plot(x,y);

One can place it in octave rc file for automatic loading.

But still it would be nice to see this bug fixed. And there is no way to run the gui as it gets stuck and eats 100% cpu.
