Hello , i have been trying to change my code to get the xticks and xlabels in this image but i dont know what to do

Here is the picture

and here is my picture with the code below it

clc
clear all
close all
 
dataset = xlsread('Final2.xlsx','Sheet1','C1:D121')
hour = dataset(:,1)
kp = [dataset(:,2)]
 
 
t=linspace(0,24,120)
subplot(5,1,1)
bar(hour,kp)
ylabel  'kp index'
 
grid on
 
xticks ([0:4:120])
xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
 
data = xlsread('Final2.xlsx','Sheet2','D2:I7201')
mins = data(:,1)
Bz = data(:,2)
subplot(5,1,2)
plot(mins,Bz)
 
 
%xticks ([s])
%xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
ylabel  'Bz(nT)'
 
 
Vx= data(:,3)
subplot(5,1,3)
plot(mins,Vx)
 
ylabel  'Vx Km\s'
 
 
Al = data(:,4)
Au = data(:,5)
subplot(5,1,4)
hold on 
plot(mins,Au)
plot(mins,Al)
ylabel 'AU & AL(nT)'
 
SYM = data(:,6)
subplot(5,1,5)
plot(mins,SYM)
ylabel 'SYM-H(nT)'
xlabel  'UT(hr)'
%xticks(0:4:120)
%xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
 
how i can change the xlabels and xticks to be   '0','4','8','12','16','20','24' and repeat itself

If you're using Matlab r2019b or later, you can use tiledlayout() to create your subplots (see examples in that link).

For earlier releases, you can use linkaxes() to set equal axis limits between all subplots. You'll need the axis handles which would look something like this

sbp(1) = subplot(5,1,1); 
% Your code
sbp(2) = subplot(5,1,2); 
% Your code
sbp(3) = subplot(5,1,3); 
% Your code etc.....
% Then, after all subplots are created, 
linkaxes(sbp, 'x')

Those are 3 different options or ideas, not 3 steps.

I actually don't recommend option 3. Options 1 and 2 are much cleaner and easier.

Here's an example of option 3. The x axis values are actually 1,2,3,4,5 but I've altering their labels to appear as 10,20,30,40,50. If you add a new value at x=40, you won't see it because it will be way off the figure.

figure()
x = [1 2 3 4 5]; 
y = [1 3 14 29 48]; 
plot(x,y, 'o')
set(gca, 'XTick', 1:5, 'XTickLabel', {'10' '20' '30' '40' '50'})

Well i dont think it worked for me , or i typed it wrong

clc
clear all
close all
 
dataset = xlsread('Final2.xlsx','Sheet1','C1:D121')
hour = dataset(:,1)
kp = [dataset(:,2)]
 
 
t=linspace(0,24,120)
sbp(1)= subplot(5,1,1)
bar(hour,kp)
ylabel  'kp index'
 
grid on
 
xticks ([0:4:120])
xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
 
data = xlsread('Final2.xlsx','Sheet2','D2:I7201')
mins = data(:,1)
Bz = data(:,2)
sbp(2)=subplot(5,1,2)
plot(mins,Bz)
 
 
%xticks ([s])
%xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
ylabel  'Bz(nT)'
 
 
Vx= data(:,3)
sbp(3)=subplot(5,1,3)
plot(mins,Vx)
 
ylabel  'Vx Km\s'
 
 
Al = data(:,4)
Au = data(:,5)
sbp(4)=subplot(5,1,4)
hold on 
plot(mins,Au)
plot(mins,Al)
ylabel 'AU & AL(nT)'
 
SYM = data(:,6)
sbp(5)=subplot(5,1,5)
plot(mins,SYM)
ylabel 'SYM-H(nT)'
xlabel  'UT(hr)'
%xticks(0:4:120)
%xticklabels({'4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24','4','8','12','16','20','24'})
 
linkaxes(sbp, 'x')
