How to put separate titles above multiple pcolor subplots

Hi all,

I have a figure of two subplots with pcolor-images. Now I want a separate title above each subplots, but somehow this doesn't work. I don't get an error, but the titles don't show. Anyone an idea how to fix this? Here is my code:

% Plot final modulus image comparison
fig = figure;
set(gcf, 'Position',  [50, 100, 1200, 400])
fig_filename = 'final_modulus_map';
ax_min = min([ref_model.mod_img(:); opt_model_k.mod_img(:)]);
ax_max = max([ref_model.mod_img(:); opt_model_k.mod_img(:)]);

subplot(1,2,1);
h=pcolor(ref_model.mod_img);
colormap(hot)
set(h, 'EdgeColor', 'none');
set(gca,'visible','off');
c = colorbar;
set(gca,'ColorScale','log')
caxis([ax_min ax_max])
c.Label.String = 'Modulus (Pa)';
title('Ref_model_modulus');

subplot(1,2,2);
h=pcolor(opt_model_k.mod_img);
colormap(hot)
set(h, 'EdgeColor', 'none');
set(gca,'visible','off');
c = colorbar;
set(gca,'ColorScale','log')  
caxis([ax_min ax_max])
c.Label.String = 'Modulus (Pa)';
title('Opt_model_modulus');
drawnow;
saveas(fig,fullfile([result_folder,'\1_modulus_maps'],fig_filename),'png')

The issue is that you are setting the axis to off with this

set(gca,'visible','off');

Your problem will be solved if you use

set(gca,'visible','on');

Notice that the title will be interpreted as a latex string, so the _ will convert the text. To avoid this you can use

title('Ref_model_modulus','interpreter','none');

Problem solved?

Thanks! So there is no option to display the title without showing the axes?

[Constantino Carlos Reyes-Aldasoro]

You can always insert other objects, but setting to visible would be the easiest. If what you do not want is the ticks on the axes themselves, you can remove those texts in particular easily like this:

>> set(gca,'xtick',[])
>> set(gca,'ytick',[])

Hope this solves the question, if it does, please accept the answer. If it does not, do let me know.

Yes that solves the problem, thanks!
