No gaps between subplot in for loop and shared subplot title

Hi,

I'd really appreciate your help.

I have plotted two subplots and would like to position the Intervention and Control subplots closer together so that there are no gaps between them on the xaxis (please see figure below).

Subsequently, I would also like the subplots on each row to share the same title i.e. 0.4mA for both the Control and Intervention subplot.

My current code is:

suplotTitle = {'0.4mA', '0.6mA', '0.8mA', '1.2mA', '1.6mA'}; 
f1=figure('units', 'normalized', 'position', [0.001 0.001 5 5]);

for ii=1:5
    s1 = subplot(6,2,2*ii-1);
    b1 = bar(conRR(2:end,1), conRR(2:end, ii+1));
    b1.FaceColor = '#D95319';
    b1.EdgeColor = 'none';
    xticks(1:1:16);
    ylim([0 70]);
    title(suplotTitle{ii});
    set(gca, 'FontSize', 11);
    box off
    
    if ii < 5
        set(gca,'XTick',[]);
    end
    
    hold all
    
    s2 = subplot(6,2,ii*2);
    b2 = bar(b9RR(2:end,1), b9RR(2:end, ii+1));
    b2.FaceColor = '#0072BD';
    b2.EdgeColor = 'none';
    xticks(1:1:16);
    title(suplotTitle{ii});
    set(gca, 'FontSize', 11);
    box off
    
    if ii < 5
        set(gca,'XTick',[]);
    end
    
    set(gca,'ytick',[])

end

t = sgtitle('Respiratory Rate');
t.FontSize = 13;
t.FontWeight = 'bold';

hL = subplot(6,2,11.5);
poshL = get(hL,'position');

lgd = legend(hL,[b1,b2],'Control','Intervention');
legend box off;
set(lgd,'position',poshL,'Orientation','horizontal', 'FontSize', 11);
axis(hL,'off');

Many thanks in advance. Cheers.

If you use subplot() then it is important that you create all of the subplot() first, and then only after the last one is created, you can set the OuterPosition of each. Record the handles of each as you create them: do not attempt to get the handle back by using subplot() again, not in this situation.

Ok, thanks, I'll give it a shot.

In terms of the shared title, I suppose with my current code, it's probably not possible to have a common title between the Control and Intervention subplots. Can you give me a hint on what I should do here?

You can use the folowing,

Example plot,

You can supress the title for ONE plot and append the title to the other plot while using the 'Position' to change its location. Eaxmple: title('Hello','Position',[2 3])
