lines through markers on legend

I am having a plot but on the legend, there are no lines through the markes. How can I fix this?.

The structure of the code is as follows:

x=-10:0.1:10;
y=cos(x);
plot(x,y,'--o','MarkerSize',5,'DisplayName',' cos(x)')
hold on
y=sin(x)
plot(x,y,'--d','MarkerSize',5,'DisplayName',' sin(x)')
hold off
legend
grid on

I changed the line width from 0.5 to 1 and it worked.

Well it’s clearly a bug!

This might have already been fixed.

 x = -10 : 0.1 : 10;
 y = cos(x);
 plot(x, y, '--o', 'MarkerSize', 5)
 hold on
 y = sin(x)
 plot(x, y, '--d', 'MarkerSize', 5)
 hold off
 legend({'cos(x)', 'sin(x)'})
 grid on

Running your code in 2020 gave me the desired result. What version are you running on?

I have v 2019b.

As you can see on the figure, the lines are not going theough the markers on the legend. Its only the markers that are showing.

Seems like a bug to me. Try contacting MathWorks Support Team.

You specified '--' option for your line style in 3rd argument of plot. If you want full lines, use '-' instead.

x=-10:0.1:10;
y=cos(x);
plot(x,y,'-o','MarkerSize',5,'DisplayName',' cos(x)')
hold on
y=sin(x)
plot(x,y,'-d','MarkerSize',5,'DisplayName',' sin(x)')
hold off
legend
grid on

But on legend its only markers that are showing as shown. Is there a way to modify the figure?

I do have lines in the legend with previous code. Seems like your MATLAB is not working correctly...
