How can I include the permil (parts per thousand) symbol in a plot with the LaTex inpreter?

Does anyone know of a way to include the permil (parts per thousand) symbol in a MATLAB plot with the LaTex interpreter?

Answer 1

Jiro Doke's solution:

slabel(['5 ',char(8240)])

[Christian Spathelf]

Thanks for the reply, but MATLAB does not accept slabel for my plot (or I am using it incorrectly). Below is an example of my code for the y-axis description:

ylabel({'$\varepsilon_{s,max}$\,[\permil]'}, 'Interpreter','latex');

hi, i ran into the same problem and used the following solution: '5^{\fontsize{7}o}/{\fontsize{7}oo}'. It's not a proper permil symbol, but the rendering is good enough. You might want to change 7 to another font size. It works with the default 'tex' interpreter.

We haven't found a way yet.

Thanks for the response Walter. I have been reduced to manually changing the symbol in Adobe Illustrator and saving the figure as EPS. Not so elegant, but it works.

As of R2014b, you can include char(8240) in any text object with interpreter 'none' or interpreter 'tex' -- but not with interpreter 'latex'

Hi Christian.

I had encountered the same problem and found a creative way to overcome it, because it seemed there's no real solution as these characters are omitted in the system.

My solution is quite straightforward. you take the location of the label after it's drawn and add a text in a proper location using the default TEX interpreter with only the permil sign. The location comes out correct in most cases, but can be adjusted if not.

ylabh=ylabel('$\mathrm{1000ln{\alpha}_{A-B}}\quad$','interpreter','latex','Color','k');
xy=ylabh.Extent;
text(xy(1)+xy(3)/2,(xy(2)+xy(4))*1,'[‰]','Rotation',90,'HorizontalAlignment','center');

-it doesn't always work with "xy(3)/2" and "xy(4)*1, so the factors (2 and 1) might need to be changed.

-note that Latex interpreter always draws in somekind of grey, therefore I specifically choose 'k' as color text color when Latex is used.

Hope this helps,

Yigal

Hey guys,

if you install the font 'LMRoman12' on your system, you can use the following syntax:

xlabel('strain \epsilon_{t} [‰]','FontName','LMRoman12-Regular')

It uses Matlab's default interpreter Tex with the font of Latex. However, the subscript position is not the same in tex and latex, so there is a small difference. Still this looks the best to me.

Have fun!

Edit: When exporting the diagram then to pdf or eps, Matlab comes back to a normal (non-latex) font. To prevent this, use the '-dsvg' option:

print('-vector',filename, '-dsvg')
