change legend line segment width in version 2018
显示 更早的评论
I am using version 2018 because it allows multicolumn legends.
plot(rand(6))
legend({'Line 1','Line 2','Line 3','Line 4','Line 5','Line 6'},'FontSize',12,'NumColumns',2)
However, I would also like to control the width of the line segment that appears in the legend. Is there a way to make it wider or shorter? The LineWidth property will change the thickness of the line. I do not want that.

The style of the legend item is inherited from the object itself, so you can make the line thicker, but only if you make the line itself thicker as well.
Also: if you're planning on sharing this code with anyone, you should be aware that the NumColumns property was introduced in R2018a, so anyone not on that release will not be able to run your code.
If that is not acceptable to you, you will have to re-implement a legend function yourself. I would advise you to take a look on the File Exchange if anybody has done something you can use.

If you can't solve your issue: having a limit on what version people can use to run your code is not necessarily a problem, but it is something you should be aware of and ideally report in your function header/help text.
