[Octave-bug-tracker] [bug #65687] [Qt Backend] LineWidth parameter ignored

[anonymous]

Follow-up Comment #9, bug #65687 (group octave):

thanks, in pdf it works indeed but not as visually appealing (the line is
outside the borders) and as you mention a few widths are supported (maybe on
my system up to 4?).
Although not perfect, I prepared a kind-of workaround.


graphics_toolkit('qt')
x = 0:0.1:10;
y = x;
plot(x, y, 'LineWidth', 0.3);
hold on
y = x + 0.5;
plot(x, y, 'LineWidth', 0.5);
y = x + 1;
plot(x, y, 'LineWidth', 0.7);
y = x + 1.5;
plot(x, y, 'LineWidth', 1.0);
y = x + 2.0;
plot(x, y, 'LineWidth', 2.0);
y = x + 2.5;
plot(x, y, 'LineWidth', 10);
y = x + 3;
plot(x, y, 'LineWidth', 20);
y = x + 3.5;
plot(x, y, 'Color', 'b', 'LineWidth', 4);
y = x + 3.55;
plot(x, y, 'Color', 'b', 'LineWidth', 4);
y = x + 3.6;
plot(x, y, 'Color', 'b', 'LineWidth', 4);
y = x + 3.65;
plot(x, y, 'Color', 'b', 'LineWidth', 4);
title('Test Plot');
xlabel('x');
ylabel('y = x');


Since using a shader representation (that would then allow any width and it
the "modern" OpenGL implementation) is a significant major change, you can
close the issue.
It would be nice to add a note in the documentation of this dependency
/limitation on OpenGL for tick lines.

many thanks for the support.

best regards,
Marco
