legend font style, f ​​and | are very close

In the lower legend f and | are very close, but in the upper one they are far. How can i set it?

[DGM]

What are the exact commands being used to set the legend strings?

[DGM]

Is that setup identical in both cases? Obviously something is being done differently, because you have two images. I can't guess what's different.

Obviously the difference between the two is that a blank is inserted between the f and the | in the one and not the other. It's not clear from the post what the Q? really is -- do you not see that or do you want some way to change the spacing besides inserting the blank, I suppose?

You can't change default kerning for a given font...it is what it is in the installed font.

If picking a font with a better spacing behavior isn't an option, you can always try to pad it using something other than a regular space.

███ ███ hair space -- thinnest nonzero-width space -- char(8202)

███ ███ thin space -- typically 1/5 em -- char(8201)

███ ███ punctuation space -- width of narrow punctuation -- char(8200)

███ ███ figure space -- tabular width of font -- char(8199)

███ ███ 6-per em space -- 1/6 em -- char(8198)

███ ███ 4-per em space -- 1/4 em -- char(8197)

███ ███ 3-per em space -- 1/3 em -- char(8196)

███ ███ em space -- em -- char(8195)

███ ███ en space -- 1/2 em -- char(8194)

███ ███ normal #32 space -- typically 1/4 em -- char(32) (or just spacebar)

One of the thinner spaces might be narrow enough to suit, but if you have a lot of things to plot, it might be quite the hassle.

EDIT

I guess there's also LaTeX

% just one test label
h = legend({'$$\left|f\right|$$'},'interpreter','latex');

this is exactly what I was looking for,

h = legend({'$$\left|f\right|$$'},'interpreter','latex');

this was helpful, thank you!

finally can you give an example of how to use the above? for example, thin space?

[Walter Roberson]

There are sequences for spacing in math mode. In my experience not all of them work in MATLAB, but some do.

thank you so much!

As per as my knowledge this is due to "FontName". Try with other FontName for e.g. Calibri etc you will see the difference.
