Why does the following not center the first line of the double-lined diagram title?

str_title = {'Line 1';'Line 2'}; title(str_title,'interpreter','latex','HorizontalAlignment', 'center');

Hi Ulrik William Nash:

Please, provide a figure of your result. It is not possible to reproduce what you describe.

Varying the 'HorizontalAlignment'-property leads to different positions of the title strings as expected:

 str_title = {'Line 1';'Line 2'};
 fh = figure;
 ah = axes;
 title(ah,str_title,'interpreter','latex',...
         'HorizontalAlignment', 'center');
 hold on
 bh = axes;
 title(bh,str_title,'interpreter','latex',...
         'HorizontalAlignment', 'left', 'color', 'green');
 ch = axes;
 title(ch,str_title,'interpreter','latex',...
         'HorizontalAlignment', 'right', 'color', 'blue');

Kind regards,

Robert

The LaTex interpreter will automatically left-align the text block, and the 'horizontalalignment' argument will align the entire block instead of each line individually. The alignment has to be set INSIDE of the LaTex environment.

I found a solution HERE that uses the LaTex tabular environment.

An example of the problem:

An example of the solution using the tabular environment:

The code looks like this:

title('\begin{tabular}{c} The first line \\ Followed by another line \end{tabular}',...
    'interpreter','latex')

For readability it could be translated to sprintf() format like this:

title_text = 'The first line \\ Followed by another line';
title(sprintf('\\begin{tabular}{c} %s \\end{tabular}',title_text),...
    'interpreter','latex')

Or broken down like this:

line1 = 'The first line';
line2 = 'Followed by another line';
title(sprintf('\\begin{tabular}{c} %s %s %s \\end{tabular}',line1,'\\',line2),...
    'interpreter','latex')
