I need the two x-axis of subplots to be equal for the following code and use a loop for describe pattern data (see the annexed file)

Thanks in advance

%=================================================%

clc;

close all;

clear;

% Define the data

pattern = [

2.46, 2.46, 2.46, 2.46, 2.46, 2.46, 2.46, 2.46, 2.46, 2.46, 2.46, 2.46, 2.46;

2.68, 2.29, 2.29, 2.29, 2.29, 2.29, 2.29, 2.29, 2.29, 2.29, 2.29, 2.29, 2.68;

NaN, 2.68, 2.5, 2.5, 2.5, 2.5, 2.5, 2.5, 2.5, 2.5, 2.5, 2.68, NaN;

NaN, NaN, 2.68, 2.3, 2.3, 2.3, 2.3, 2.3, 2.3, 2.3, 2.68, NaN, NaN;

NaN, NaN, NaN, 2.68, 2.4, 2.4, 2.4, 2.4, 2.4, 2.68, NaN, NaN, NaN;

NaN, NaN, NaN, NaN, 2.68, 2.5, 2.5, 2.5, 2.68, NaN, NaN, NaN, NaN;

NaN, NaN, NaN, NaN, NaN, 2.68, 2.57, 2.68, NaN, NaN, NaN, NaN, NaN;

NaN, NaN, NaN, NaN, NaN, NaN, 2.68, NaN, NaN, NaN, NaN, NaN, NaN;

];

% Define the data for (x, g)

x = [-6:6];

g = [-0.002 -0.004 -0.005 -0.008 -0.008 -0.014 -0.014 -0.014 -0.008 -0.008 -0.005 -0.004 -0.002];

% Define positions for text

[row, col] = find(~isnan(pattern));

% Define cell size

cellSize = 1;

% Define colors for each unique value

unique_values = unique(pattern(~isnan(pattern)));

colors = parula(length(unique_values)); % Change 'parula' to any colormap you prefer

% Create a new figure

figure;

% Plot the existing pattern

subplot(2, 1, 1); % Adjust subplot dimensions as needed

% Plot the square cells with distinct colors for each value

for i = 1:numel(row)

value = pattern(row(i), col(i));

color_index = find(unique_values == value);

rectangle('Position', [col(i)-0.5, row(i)-0.5, cellSize, cellSize], 'EdgeColor', 'k', 'FaceColor', colors(color_index,:));

text(col(i), row(i), num2str(value), ...

'HorizontalAlignment', 'center', 'VerticalAlignment', 'middle', 'FontSize', 10);

end

grid on

% Set axis limits

xlim([min(x), max(x)]);

ylim([0.5, size(pattern, 1) + 0.5]);

axis equal;

set(gca, 'YDir', 'reverse');

title('(x, g) Pattern');

% Plot (x, g)

subplot(2, 1, 2); % Adjust subplot dimensions as needed

plot(x, g, '-o');

grid on;

xlabel('x');

ylabel('g');

title('(x, g) Plot');

xlim([min(x), max(x)]); % Set the same x-axis limits as the pattern plot

% Adjust the position of subplots to make them visually aligned

set(gca, 'Position', get(gca, 'Position') + [0 0.05 0 0]);

Use linkaxes to link the two x axis limits. When the limits of one x-axis changes, the other will adjust.

I made 6 changes to your code

store the axes handles in the output of subplot() (x2)
remove setting xlim on both axes (x2)
Add linkaxes() toward the end
Set xlim to either axes after linking axes

% Define the data
