Hi
A slight modification of your script does not work on my El Capitan Octave (homebrew version 4.0.2). The problem: octave/gnuplot can only draw dotted grid lines, which are almost impossible to see with the default 0.5 linewidth. Here is a demonstration script.
% test_octave_graphics.m - to demonstrate an octave/gnuplot problem graphics_toolkit('gnuplot'); x = 0 : 0.1 : 3.5; y = sin(x); close all; figure; plot(x, y); axis([0, 3.5, 0, 1.5], "equal"); set(gca, "xgrid", "on", "ygrid", "on", ... "gridlinestyle", "-", ... "xtick", [0 : 0.5 : 3.5], ... "ytick", [0 : 0.5 : 1.5] ... );
Change the first line to graphics_toolkit(‘qt’); and you will see solid grid lines —- as you should.
What kind if terminal your gnuplot is using? With either qt or x11 terminals I get a reasonably good looking picture (see attached). You can select terminal by using setenv("GNUTERM", "qt")

What is your point, Dmitri? You show two screen shots with dotted gridlines. My code says to draw solid gridlines: “gridstyle”, “-“, ...
That is the problem with my octave/gnuplot. It can’t draw solid gridlines. Here is a plot of the above code with the first line changed to graphics_toolkit(‘qt’). These are what I call “solid” gridlines.
