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
quiver(Y(1:1:nrow,indcol:1:ncol),X(1:1:nrow,indcol:1:ncol),umyvec2(1:1:nrow,indcol:1:ncol), umxvec2(1:1:nrow,indcol:1:ncol),1)
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))
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)')
colorbar
elseif ij == 3
indicol = find(hcontour3,1,'first');
[indrow indcol] = find(hcontour3 == hcontour3(indicol));
subplot(4,1,3)
yline(source_height*dy+dy,'--', 'Source')
hold on
quiver(Y(1:1:nrow,indcol:1:ncol),X(1:1:nrow,indcol:1:ncol),umyvec3(1:1:nrow,indcol:1:ncol), umxvec3(1:1:nrow,indcol:1:ncol),1)
hold on
contour(Y(:,indcol:ncol), X(:,indcol:ncol), hcontour3(:,indcol:ncol))
title(sprintf('Contour map of the fluid thickness at time = %2.0f%% of the 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)')
colorbar
elseif ij == 4
indicol = find(hcontour4,1,'first');
[indrow indcol] = find(hcontour4 == hcontour4(indicol));
subplot(4,1,4)
colorbar
yline(source_height*dy+dy,'--', 'Source')
hold on
quiver(Y(1:1:nrow,indcol:1:ncol),X(1:1:nrow,indcol:1:ncol),umyvec4(1:1:nrow,indcol:1:ncol), umxvec4(1:1:nrow,indcol:1:ncol),1)
hold on
contour(Y(:,indcol:ncol), X(:,indcol:ncol), hcontour4(:,indcol:ncol))
title(sprintf('Contour map of the fluid thickness at time = %2.0f%% of the max time', times(ij)*100))
subtitle(sprintf('Inline 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)')
else

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
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1617863/image.png)
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
Thank You,
Gautam Murthy
