How to put en dashes instead of hyphens for a negative values on the x,y-axis and colorbar numbers?

Left picture has correct view: en dashes are used on the y-axis negative numbers.

Right picture is what I usually have: hyphens are used on the y-axis negative numbers.

I need to change this in a purpose for the publication, it`s an important note. I checked already everything and didn`t find any info besides the latex interpreter for the text function.

The material I find and some tests suggest using yticklabels that have two hyphens instead of one, and set the tick label interpreter to latex. Do not enclose the tick labels in dollar signs. '--20' not '$--20$'

Tnank you really for noting this detail! So, this problem can be solved only by manual changing of the axis ticks? Is there any "auto" solution like font changing?

[Walter Roberson]

I am sure that font changing would not be enough, as even if you used a different font, it would be necessary to be able to distinguish between hyphen and en-dash.

ax = gca;
yticklabels(ax, strrep(yticklabels(ax),'--','–'));
set(ax,'ticklabelinterpreter','none')  %or 'tex' but not 'latex'

The replacement character is the unicode en-dash character, U+2013

Note: the 'none' interpreter and 'tex' interpreter support unicode, but latex interpreter does not.

xticklabels(ax, strrep(xticklabels(ax),'--','–'));

cb = colorbar();
cb.TickLabels = strrep(cb.TickLabels, '-', '–');

It`s strange but it finally works only as in the colorbar example, double dash doesn`t make any effect with any interpreter.

set(ax,'ticklabelinterpreter','none')  %or 'tex' but not 'latex'
yticklabels(ax, strrep(yticklabels(ax),'-','–'));
xticklabels(ax, strrep(xticklabels(ax),'-','–'));
cb = colorbar();
cb.TickLabels = strrep(cb.TickLabels, '-', '–');

[Walter Roberson]

I ended up not using double dash. That worked for title() but not for ticks. For ticks replacement with endash character seemed to work.

Tnank you again for your help!

Hi Walter,

I have the same problemI want to replace the hyphens with en dashes in a plot. I have the plot ready. I copy the code you provided in my command window but it did not work. Any suggestion.

Thanks

For me it is working with the 'tex' interpreter
