- 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

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;

% Define the data
pattern = [

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

😳 sorry about that!
@Moustafa Abedel Fattah please note my mistake that Voss pointed out

No problem, I just wanted it to be clear to OP that the changes you listed were relative to my answer.

Remove axis equal. Shift the rectangles and texts to the left by 7. Increase the width of the x-limits by 1 (0.5 on each side), to account for the width of a rectangle.
