I need a square subplots and the colorbar label needs to move to top of the bar. Could some one help me?

set(0,'DefaultAxesFontName','TimesNewRoman');

set(0,'DefaultAxesFontSize',16);

set(0,'DefaultAxesFontWeight','bold')

figure

fig = gcf;

% fig.Position = [0, 0, 10000, 4000];

subplot(2,3,1)

imagesc(randn(10,10))

subplot(2,3,2)

imagesc(randn(10,10))

subplot(2,3,3)

imagesc(randn(10,10))

subplot(2,3,4)

imagesc(randn(10,10))

subplot(2,3,5)

imagesc(randn(10,10))

subplot(2,3,6)

imagesc(randn(10,10))

cbar = colorbar;

cbar_title = 'amp';

cbar.Label.String = cbar_title;

% Adjust the layout to make room for the color bar

set(gcf, 'Position', [100, 100, 1100, 800]);

cbar.Position = [0.92, 0.1, 0.02, 0.8];

@Dyuman Joshi, the plots have equal axes, but they are not ("physically") the same dimension. (See my solution.)

@Dyuman Joshi, I cheked that too, to align my colorbar label. But the code you have given depends on clims. And not working on all the cases.

One way is to add axis square after each imagesc call:

set(0,'DefaultAxesFontName','TimesNewRoman');

set(0,'DefaultAxesFontSize',16);

set(0,'DefaultAxesFontWeight','bold')

figure

fig = gcf;

% fig.Position = [0, 0, 10000, 4000];

subplot(2,3,1)

imagesc(randn(10,10))

axis square

subplot(2,3,2)

imagesc(randn(10,10))

axis square

subplot(2,3,3)

imagesc(randn(10,10))

axis square

subplot(2,3,4)

imagesc(randn(10,10))

axis square

subplot(2,3,5)

imagesc(randn(10,10))

axis square

subplot(2,3,6)

imagesc(randn(10,10))

axis square

cbar = colorbar;

cbar_title = 'amp';

cbar.Label.String = cbar_title;

% Adjust the layout to make room for the color bar

set(gcf, 'Position', [100, 100, 1100, 800]);

cbar.Position = [0.92, 0.1, 0.02, 0.8];

You might not want to bother with this, because you presumably have a working solution using subplot, but in the future you might also consider using the tiledlayout function to create plots of this type.

@Dyuman Joshi, I'm not sure about your perception, but your subplots are rectangular in shape; mine are square.

Take a look at the documentation for the axis command (which governs both axis limits and axis scaling), specifically the two different styles called equal and square.

The default axes are equal, with DataAspectRatio = [1 1]. But they are not square, because their PlotBoxAspectRatio is not [1 1]. The axis square command does that. See the difference side-by-side:

N=7;

tiledlayout(1,2)

nexttile

rng default

scatter(rand(N,1),rand(N,1))

nexttile

rng default

scatter(rand(N,1),rand(N,1))

axis square

@Kalasagarreddi Kottakota, you can adjust the position of the colorbar label using the Label.Position property. For example in your case

cbar.Label.Position = [2.7 2.0 0]

moves it up near the top.
