Displaying Colourbars in subplots

Im trying to get a colour bar to show up for each one of these subplots, or one big one. I have tried using tiledlayout, the colorbar function and other online answers, but so far nothing is working. The strange thing is I can manually add a colorbar in the final figure window after the calculation, but they should be there automatically.

I haver attached my code below.

for ij = 1:length(times)

            if ij == 1
                indicol = find(hcontour1,1,'first');
                [irow indcol] = find(hcontour1 == hcontour1(indicol));
                indirow = find(hcontour1',1,'first');
                [indrow icol] = find(hcontour1 == hcontour1(indirow));
                subplot(4,1,1)
                colorbar
               
              
                yline(source_height*dy+dy,'--', 'Source')
                hold on
                quiver(Y(indrow:1:nrow,indcol:1:ncol),X(indrow:1:nrow,indcol:1:ncol),umyvec1(indrow:1:nrow,indcol:1:ncol), umxvec1(indrow:1:nrow,indcol:1:ncol),1)
                hold on
                contour(Y(indrow:nrow,indcol:ncol), X(indrow:nrow,indcol:ncol), hcontour1(indrow:nrow,indcol:ncol))
                title(sprintf('Contour map of the fluid thickness at time = %2.0f%% of max time', times(ij)*100))
                subtitle(sprintf('Incline angle of %2.0f degrees & an initial source fluid thickness of %1.0fm', angles(ii),thickness(jj)))
                xlabel('Transverse Flow Dispersion (m)')
                ylabel('Flow length(m)')
                
            
            elseif ij == 2
                indicol = find(hcontour2,1,'first');
                [indrow indcol] = find(hcontour2 == hcontour2(indicol));
                subplot(4,1,2)
                yline(source_height*dy+dy,'--', 'Source')
                hold on

                hold on
                contour(Y(:,indcol-10:ncol), X(:,indcol-10:ncol), hcontour2(:,indcol-10:ncol))
                title(sprintf('Contour map of the fluid thickness at time = %2.0f%% of the max time', times(ij)*100))

Hello, Johnny

I tried simulating you code and I am able to see the colorbar for the individual subplots. The figure below shows that output that I get when I run my code

As you can see, the colorbar appears adjacent to all the constituent subplots

Below is the code I used to get the output

[X,Y,Z] = peaks;
for ij = 1:4

    if ij ==1
        a = 5*rand(1,20);
        b = 5*rand(1,20);
        c = 1:5;
        d = 5*rand(1,20);
        e = 5*rand(1,20);
        subplot(4,1,1)
        colorbar
        
        yline(2.5, '--', 'Source')
        hold on
        quiver(a,b,d,e,1);
        hold on
        contour(X,Y,Z,20)
        title(sprintf('Contour map of the fluid thickness at time = 20 of max time'))
        subtitle(sprintf('Incline angle of 10 degrees & an initial source fluid thickness of 20'))
        xlabel('Transverse Flow Dispersion (m)')
        ylabel('Flow length(m)')
   
    elseif ij ==2
        a = 5*rand(1,20);
        b = 5*rand(1,20);
        c = 1:5;
        d = 5*rand(1,20);
        e = 5*rand(1,20);
subplot(4,1,2)
        yline(2.5, '--', 'Source')
        hold on
        quiver(a,b,d,e,1);
        hold on
        contour(X,Y,Z,20)
        title(sprintf('Contour map of the fluid thickness at time = 20 of max time'))
        subtitle(sprintf('Incline angle of 10 degrees & an initial source fluid thickness of 20'))
        xlabel('Transverse Flow Dispersion (m)')
        ylabel('Flow length(m)')

        colorbar
    
    elseif ij ==3
        a = 5*rand(1,20);
        b = 5*rand(1,20);
        c = 1:5;
        d = 5*rand(1,20);
        e = 5*rand(1,20);
        subplot(4,1,3)
        yline(2.5, '--', 'Source')
        hold on
        quiver(a,b,d,e,1);
        hold on
        contour(X,Y,Z,20)
        title(sprintf('Contour map of the fluid thickness at time = 20 of max time'))
        subtitle(sprintf('Incline angle of 10 degrees & an initial source fluid thickness of 20'))
        xlabel('Transverse Flow Dispersion (m)')
        ylabel('Flow length(m)')

        colorbar

    elseif ij ==4
        a = 5*rand(1,20);
        b = 5*rand(1,20);
        c = 1:5;
        d = 5*rand(1,20);
        e = 5*rand(1,20);
        subplot(4,1,4)
        colorbar
        yline(2.5, '--', 'Source')
        hold on
        quiver(a,b,d,e,1);
        hold on
        contour(X,Y,Z,20)
        title(sprintf('Contour map of the fluid thickness at time = 20 of max time'))
        subtitle(sprintf('Incline angle of 10 degrees & an initial source fluid thickness of 20'))
        xlabel('Transverse Flow Dispersion (m)')
        ylabel('Flow length(m)')
    end
end

Please let me know if I am missing something or misinterpreting someting in your question

Here is a link to the MathWorks Documentation page for more information on the "colorbar" function
